The core stage of the Space Launch System (SLS) rocket for NASA’s Artemis I mission has been placed on the mobile launcher in between the twin solid rocket boosters inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center. The boosters attach at the engine and intertank sections of the core stage. Serving as the backbone of the rocket, the core stage supports the weight of the payload, upper stage, and crew vehicle, as well as carrying the thrust of its four engines and two five-segment solid rocket boosters.
After the core stage arrived on April 27, engineers with Exploration Ground Systems and contractor Jacobs brought the core stage into the VAB for processing work and then lifted it into place with one of the five overhead cranes in the facility.
Once the core stage is stacked alongside the boosters, the launch vehicle stage adapter, which connects the core stage to the interim cryogenic propulsion stage (ICPS), will be stacked atop the core stage and quickly followed by the ICPS.
Artemis I will be an uncrewed test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA aims to land the first woman and first person of color on the Moon in 2024 and establish sustainable lunar exploration by the end of the decade.
NASA and SpaceX have adjusted target launch and return dates for upcoming crew missions to and from the International Space Station based on visiting vehicle traffic.
NASA’s SpaceX Crew-3 mission now is targeting launch no earlier than Sunday, Oct. 31, with NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron and ESA (European Space Agency) astronaut Matthias Maurer. Crew-3 will launch on a new Crew Dragon spacecraft from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to begin a six-month science mission at the space station.
Crew-3 astronauts will arrive at the space station for a short handover period with the Crew-2 astronauts and other crew members on Expedition 66. Crew-2 NASA astronauts Shane Kimbrough and Megan McArthur, JAXA (Japan Aerospace Exploration Agency) astronaut Aki Hoshide, and ESA astronaut Thomas Pesquet are targeting early-to-mid November for a return to Earth inside Crew Dragon Endeavour off the coast of Florida.
Following Crew-3, the next crew rotation mission is targeted for no earlier than mid-April 2022 with the partner spacecraft and launch vehicle to be determined at a later date.
NASA’s Commercial Crew Program is working with industry through a public-private partnership to provide safe, reliable, and cost-effective transportation to and from the International Space Station, which will allow for additional research time and will increase the opportunity for discovery aboard humanity’s testbed for exploration. The space station remains the springboard to space exploration, including future missions to the Moon and eventually to Mars.
The launch of a United Launch Alliance Atlas V 551 rocket carrying the Space Test Program-3 (STP-3) mission for the U.S. Space Force’s Space and Missile Systems Center has been delayed to evaluate launch vehicle readiness. A new launch date will be released when it is available. NASA’s Laser Communications Relay Demonstration (LCRD) is a payload on STPSat-6, the primary spacecraft on STP-3, and will demonstrate laser communications technologies from geosynchronous orbit about 22,000 miles above Earth upon launch.
More than 7,300 pounds of science and research, crew supplies, and vehicle hardware are on their way to the International Space Station, following the picture-perfect launch of SpaceX’s 22nd resupply services mission. SpaceX’s upgraded Dragon spacecraft launched atop the company’s Falcon 9 rocket from Kennedy Space Center’s Launch Complex 39A in Florida, marking the first flight of this Dragon spacecraft. Liftoff occurred at 1:29 p.m. EDT.
“The vehicles that deliver our crews, they do a great job of getting our crews there safely to and from station, but their cargo capacity is very limited,” said Jeff Arend, manager of the International Space Station Office for Systems Engineering and Integration. “We couldn’t conduct all of the science we do, as well as provide for our crew members, without our cargo resupply vehicles. Our cargo flights are vital to maintaining and fully utilizing our orbiting laboratory.”
The second launch for SpaceX under NASA’s second Commercial Resupply Services contract, the mission will deliver a variety of science and research experiments, including one that could help develop better pharmaceuticals and therapies for treating kidney disease on Earth, a study of cotton root systems that could identify plant varieties that require less water and pesticides, and an experiment using bobtail squid as a model to examine the effects of spaceflight on interactions between beneficial microbes and their animal hosts.
Also included in the delivery are the first two of six new roll-out solar arrays. These will be extracted by a robotic arm and installed by astronauts during a series of spacewalks this summer.
“Over time, our solar arrays age. The first set of arrays have been up there over 20 years,” Arend said. “This augmentation is going to help us fully extend the life of the International Space Station and fully execute our full suite of research as we move forward. And probably most importantly, it allows us to power more science and research, especially in the form of future exploration systems and commercial users.”
About two-and-a-half minutes after liftoff, the Falcon 9’s first stage separated from the rocket, and a few minutes later, successfully landed on the drone ship “Of Course I Still Love You” in the Atlantic Ocean. Next, Dragon separated from the rocket completely. The spacecraft is now in orbit, traveling solo to the space station.
Dragon is slated to arrive at the orbiting laboratory on Saturday, June 5, and will autonomously dock to the space-facing port on the station’s Harmony module. Expedition 65 Flight Engineers Shane Kimbrough and Megan McArthur of NASA will monitor docking operations, and live coverage will air on NASA TV and the agency’s website beginning at 3:30 a.m. EDT. Docking is targeted for 5 a.m.
Dragon will spend more than a month attached to the space station, after which it will return to Earth with up to 5,300 pounds of research and return cargo, splashing down in the Atlantic Ocean off the eastern coast of Florida.
A SpaceX Falcon 9 rocket, topped with the company’s upgraded Dragon spacecraft, stands ready for launch at NASA Kennedy Space Center’s Launch Complex 39A in Florida. Following a prelaunch news conference held at Kennedy, NASA and SpaceX remain on track for the company’s 22nd cargo resupply mission to the International Space Station.
“Just a couple of months ago, the Crew-2 crew got on board, and now they’re waiting to receive all this science and do it, so it’s really exciting for us at SpaceX,” said Sarah Walker, director of Dragon Mission Management at SpaceX. “Thanks to NASA for your ongoing partnership; this is an exciting mission, and tomorrow is just one more example of a long history that we’re thankful for.”
Liftoff is slated to occur at 1:29 p.m. EDT Thursday, June 3, and weather officials continue to predict a 60% chance of favorable weather conditions for launch. The primary weather concerns for liftoff are the cumulus cloud rule and flight through precipitation.
“It’s Florida, it’s summertime, and that means showers and storms; the main issue would be a few of those showers that come off of the coast and head toward our launch facility,” said Mark Burger, launch weather officer with Cape Canaveral Space Force Station’s 45th Weather Squadron. “However, given that there’s quite a lot of real estate between each one of those showers, I do think there’s still a better-than-average chance that we’ll be able to thread the needle and get in a good launch opportunity for tomorrow.”
Dragon will deliver more than 7,300 pounds of science and research investigations, supplies, and hardware to the orbiting laboratory and its crew. A few of the investigations arriving in Dragon’s pressurized capsule include an experiment that could help develop better pharmaceuticals and therapies for treating kidney disease on Earth, a study of cotton root systems that could identify plant varieties that require less water and pesticides, and an experiment using bobtail squid as a model to examine the effects of spaceflight on interactions between beneficial microbes and their animal hosts.
Also included in that delivery are the first two of six new roll-out solar arrays, which will be installed during spacewalks later this month to upgrade the station’s power capabilities.
“With seven crew members on board, the team is really just knocking it out of the park,” said Joel Montalbano, program manager for NASA’s International Space Station Program Office. “The utilization and research that they’re able to do on board, the commercialization efforts, the technology developed for our lunar program – it’s really a pleasure to watch these guys. They’re excited for the mission, and they’re excited to see these two new solar arrays on board.”
About 12 minutes after launch, Dragon will separate from the Falcon 9 rocket’s second stage, starting its solo journey to the space station. The uncrewed spacecraft is scheduled to arrive at the station on Saturday, June 5. Upon its arrival, Dragon will autonomously dock to the space station’s Harmony module, with Expedition 65 Flight Engineers Shane Kimbrough and Megan McArthur of NASA monitoring operations.
After spending about one month attached to the station, Dragon will autonomously undock to begin its journey home. Upon re-entering Earth’s atmosphere, the spacecraft will splash down in the Atlantic Ocean off the eastern coast of Florida, bringing with it experiment samples and return cargo.
RamSat, a small research satellite, or CubeSat, developed by Robertsville Middle School in Oak Ridge, Tennessee, will launch aboard SpaceX’s 22nd Commercial Resupply Services (CRS-22) mission. Lifting off from NASA’s Kennedy Space Center in Florida on June 3 at 1:29 p.m. EDT, CRS-22 will carry 7,300 pounds of cargo, science, and research to the International Space Station. The RamSat CubeSat onboard is on a mission to study forest regrowth in the Gatlinburg area following the 2016 wildfires.
This satellite will use small cameras to capture pictures of growing forests and radio communication to send those images to ground control in Robertsville Middle School’s STEM Classroom. Students will operate the mission using amateur radio frequencies to listen for RamSat flying overhead, send commands to control the spacecraft, and gather image data and information about the spacecraft’s health. RamSat’s mission, which could last up to 18 months, will begin when it deploys from the space station into its own orbit 250 miles above Earth.
The concept for RamSat was created by students, Tyler Dunham and Aidan Hilliard. During its approximately five-year development, over 150 students have had the opportunity to work on the CubeSat. Robertsville Middle School was selected by NASA’s CubeSat Launch Initiative (CSLI) in 2018. CSLI enables the launch of CubeSats designed, built, and operated by students, teachers and faculty, as well as NASA centers and nonprofit organizations. Managed by NASA’s Launch Services Program, the Educational Launch of Nanosatellites (ELaNa) missions provide a deployment opportunity or ride-share launch to space for CubeSats selected by CSLI. RamSat will launch as the sole CubeSat of the agency’s 36th ELaNa mission (ELaNa 36).
