On NASA’s next Educational Launch of Nanosatellites (ELaNa) mission, a pair of small satellites, called CubeSats, will hitch a ride on SpaceX’s 27th commercial resupply services mission to the International Space Station for NASA.

The ELaNa 50 complement of CubeSats will launch aboard the SpaceX Falcon 9 and Dragon spacecraft this March, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, along with additional supplies, equipment, and science investigations to be delivered to the crew aboard the station.

The university-built CubeSats are going to space as part of NASA’s CubeSat Launch Initiative (CSLI). Once deployed, the CubeSats will demonstrate technologies to conduct atmospheric experiments and reduce space debris, as well as provide people on Earth the opportunity for an immediate and powerful connection with an object in space.

First Launch for The Natural State

The CSLI program will launch its first CubeSat from Arkansas. Developed at the University of Arkansas, Fayetteville, ARKSAT-1, is a CubeSat measuring 1U, or unit, (about 4 inches cubed). It will illuminate an LED from orbit and use a ground spectrometer to track and perform atmospheric measurements.

“It might be the first time this instrument technology is purposefully designed to be done with a CubeSat,” said Adam Huang, principal investigator. “It could be developed into future satellite-based systems using cooperative formations of CubeSats.”

ARKSAT-1’s secondary objective sets out to demonstrate a way to help alleviate the problem of space debris with a lightweight Solid State Inflatable Balloon (SSIB) that can be used to deorbit small satellites after a mission ends. When the balloon on ARKSAT-1 inflates, it will greatly increase the ARKSAT-1’s aerodynamic drag, thereby helping the satellite re-enter and disintegrate safely in Earth’s atmosphere. If successful, the SSIB technology could help reduce the amount of time a small satellite remains “space junk” in low-Earth orbit after its mission has ended.

Helping Others See the Light

LightCube, a 1U CubeSat developed by Arizona State University, Tempe, in collaboration with Vega Space Systems and Mexico’s CETYS Universidad, features a flash bulb that can be controlled remotely by amateur radio operators on Earth who will be able to activate the satellite to produce a brief flash visible from the ground.

“LightCube provides potential users worldwide with the opportunity to telecommand a spacecraft and observe a tangible and immediate response in the night sky,” said Jaime Sanchez de la Vega, principal investigator. “The team hopes that this process inspires users to learn about space, satellites, and related concepts.”

The flash will appear at a brightness similar to the International Space Station, and several commonly available smartphone and computer apps will show when LightCube is overhead and where to look in the sky to see its flash.

Considering the observational environment, the LightCube team conducted an in-depth assessment to confirm that the brief flashes generated will not have a significant impact on astronomy.

In selecting the CubeSats for ELaNa 50, CSLI continues furthering its goal of providing U.S. educational institutions, nonprofits with an education/outreach component, informal educational institutions (museums and science centers), and NASA centers with access to space at a low cost. Through CSLI, NASA’s Launch Services Program pairs selected CubeSats with launches best suited for each CubeSat’s mission and ready date, taking into consideration the planned orbit and any special constraints the CubeSat’s mission may have.

Launch Day: Weather is 100% Favorable for SWOT Launch

Meteorologists with the U.S. Space Force’s Space Launch Delta 30 Weather Squadron are predicting a 100% chance of favorable weather conditions for launch, with no primary weather concerns.

NASA Updates SWOT Launch Date, TV Coverage

NASA, the French space agency Centre National d’Études Spatiales, and SpaceX now are targeting 3:46 a.m. PST on Friday, Dec. 16, for launch of the Surface Water and Ocean Topography (SWOT) mission.

After SpaceX’s Falcon 9 rocket went vertical on the pad at Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California, teams identified moisture in two Merlin engines on the rocket’s first stage booster. Teams completed inspections of the rocket’s engines today, but will use the additional time to complete data reviews and analysis before a launch attempt.

The SWOT satellite is healthy, and the weather forecast remains favorable for liftoff on Friday morning. Live launch coverage will begin at 6 a.m. EST (3 a.m. PST) on Friday on NASA Television, YouTube, Twitter, the NASA app, and the agency’s website.

NASA Awards Phantom Launch Services Task Order for CSLI Mission

NASA logo

NASA has awarded Phantom Space Corp. four task orders to launch four CubeSat Launch Initiative missions as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract. The CubeSats will launch no earlier than 2024 on Phantom’s Daytona rocket.

Building on NASA’s previous procurement efforts to foster development of new launch vehicles for NASA payloads, VADR provides Federal Aviation Administration-licensed commercial launch services for payloads that can tolerate higher risk. By using a lower level of mission assurance, and commercial best practices for launching rockets, these highly flexible contracts help broaden access to space through lower launch costs.

Phantom is one of 13 companies NASA selected for VADR contracts in 2022. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contracts.

Four small, shoebox-sized satellites are being prepared to launch to the International Space Station as part of NASA’s Educational Launch of Nanosatellites (ELaNa) 49 mission. The small satellites, called CubeSats, will study a range of topics – from satellite communication methods to space weather to testing technology for robotic assembly of large telescopes.

The CubeSats will hitch a ride on the SpaceX Falcon 9 rocket and Dragon spacecraft set to deliver additional science, crew supplies, and hardware to the station during the company’s 26th commercial resupply services mission for NASA. Launch is targeted at 4:19 p.m. EST from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.

Satellite Communications

The first U.S. high school to send a CubeSat to space back in 2013, Thomas Jefferson High School for Science and Technology’s Research and Education Vehicle for Evaluating Radio Broadcasts satellite aims to study the use of iridium as a primary radio communication method. Additionally, the satellite will demonstrate using a passive magnet onboard and the Earth’s magnetic field for stabilization rather than using an attitude determination and control system for pointing accuracy and stabilization for iridium. What makes this satellite even more notable is that it was a system’s engineering project. The students selected space-grade parts, wired the electronics for the satellite, wrote the drivers to control the different systems, and coded the flight software.

“What’s special about TJREVERB isn’t necessarily the mission, it’s what we did. These kids literally built a satellite the way the industry would build a satellite; we selected parts from vendors and got those parts to work together,” said Kristen Kucko, robotics lab director and the school’s space faculty advisor. “This is an engineering feat.”

Structure Testing

The University of Michigan’s Measurement of Actuator Response In Orbit (MARIO) is a technology demonstration that will show how test structures made of a piezoelectric material – a type of material that bends when electricity is applied and can also generate electricity when bent – perform in low-Earth orbit. This will allow the spacecraft to bend or move without any rotating parts and could one day be used to point and adjust telescope mirrors more accurately.

Space Weather

NASA Goddard Space Flight Center’s Plasma Enhancement in The Ionosphere-Thermosphere Satellite (petitSat) will study density irregularities in the Earth’s ionosphere – a tiny fraction of the atmosphere made of plasma, or ionized gas. During long distance radio communication, the ionosphere reflects radio waves back to Earth. Disturbances in the upper atmosphere can change the shape of the ionosphere, creating a funhouse mirror effect and distorting these radio waves. The mission will use two instruments to measure the structure and motion of plasma in the ionosphere resulting from these changes in the upper atmosphere to better understand how these affect satellite communications.

NASA Marshall Space Flight Center’s Scintillation Prediction Observations Research Task (SPORT) will also look to the ionosphere to study space weather. The joint mission between the U.S. and Brazil will examine the formation of plasma bubbles, which sometimes scatter radio signals. Understanding how these bubbles are formed and how their evolution impacts communication signals can help scientists improve the reliability of communication and navigation systems.

“The more we learn about space weather – and how to predict it – the better we can protect our astronauts, spacecraft, and technology,” said Shelia Nash-Stevenson, SPORT project manager.

All of these were selected through NASA’s CubeSat Launch Initiative (CSLI), which provides U.S. educational institutions, nonprofits with an education/outreach component, informal educational institutions (museums and science centers), and NASA centers with access to space at a low cost. Once the CubeSat selections are made, NASA’s Launch Services Program works to pair them with a launch that is best suited to carry them as auxiliary payloads, taking into account the planned orbit and any constraints the CubeSat missions may have.

Psyche Mission Update

This illustration, updated in April 2022, depicts NASA’s Psyche spacecraft. The Psyche mission will explore a metal-rich asteroid of the same name that lies in the main asteroid belt between Mars and Jupiter. The spacecraft will orbit the asteroid – also shown in this illustration – for nearly two years to investigate its composition. Credit: NASA/JPL-Caltech/ASU

NASA’s Psyche mission team continues to assess ongoing issues with the spacecraft’s flight software. The team is evaluating its ability to meet a schedule to launch in 2022 – the current launch period is Sept. 20 to Oct. 11. If it is determined that launch in 2022 is not possible, a full range of actions for how to proceed will be considered.

TROPICS Mission Update

After a nominal first stage flight, the upper stage of the rocket shut down early and failed to deliver the TROPICS CubeSats to orbit.

NASA’s Launch Services Program, who managed the launch service for the mission, continues to work with emerging launch providers to deliver low-cost science missions into orbit through contracts that align with commercial practices, using less NASA oversight to achieve lower launch costs.

Small satellites and Class D payloads tolerate relatively high risk and serve as an ideal platform for technical and architecture innovation, contributing to NASA’s science research and technology development. The program offers opportunity for industry developing new launch capabilities.

Liftoff!

Two TROPICS CubeSats have lifted off atop an Astra Rocket 3 from Space Launch Complex 46 at Cape Canaveral Space Force Station in Florida today, June 12, 2022. Launch occurred at approximately 1:43 p.m. EDT.

New T-0 Time Established for Today’s TROPICS Launch

Astra has completed final liquid oxygen conditioning and resumed countdown for the launch of its Rocket 3, carrying two of NASA’s TROPICS CubeSats. Liftoff currently is scheduled for today at 1:43 p.m. EDT.

Mission Facts About TROPICS

Each TROPICS satellite is identical – a 3U CubeSat about the size of a loaf of bread and weighing about 12 lbs.

The TROPICS CubeSat payload is a spinning microwave radiometer with highly integrated, compact microwave receiver electronics.

TROPICS satellite measures microwave frequencies ranging from about 90 to 205 gigahertz, which can monitor the atmospheric emissions made by water vapor, oxygen, and clouds in the atmosphere.

TROPICS target altitude is 550 kilometers, and pairs of CubeSats will have three slightly different low-Earth orbits, all at an angle about 30 degrees above the equator.

The TROPICS Pathfinder satellite, a proof-of-concept CubeSat that launched in June of 2021, has captured images of several tropical cyclones, such as Hurricane Ida over the United States, Cyclone Batsirai over Madagascar, and Super Typhoon Mindulle over eastern Japan. The pathfinder satellite has also provided the TROPICS research team an opportunity to fine tune the satellites’ software and operational procedures before the constellation launches. In addition, the pathfinder has already been calibrated and will be able to serve as a calibration reference for the rest of the TROPICS constellation satellites. The TROPICS pathfinder helps the TROPICS CubeSats start producing useful data quickly.

Astra’s Rocket 3 is an expendable, vertically-launched two stage rocket that uses liquid oxygen and kerosene as propellants. It has an overall length of 43 feet and is 52 inches in diameter. Astra designed it to fit inside a standard shipping container. Rocket 3 has five engines on its first stage, and one engine on its second stage.

TROPICS is an Earth venture instrument mission – science-driven, competitively selected, low-cost missions that provide opportunity for investment in innovative Earth science to enhance our capability to better understand the current state of the Earth system and to enable continual improvement in the prediction of future changes.

The TROPICS team is led by Principal Investigator Dr. William Blackwell at Massachusetts Institute of Technology’s (MIT) Lincoln Laboratory in Lexington and includes researchers from NASA, the National Oceanic and Atmospheric Administration (NOAA), and several universities and commercial partners.

NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida manages the launch service.
