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, 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.
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.
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.”
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.
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.

SpaceX’s Dragon spacecraft – carrying more than 5,800 pounds of critical science, hardware, and crew supplies – is on its way to the International Space Station following a successful launch from NASA’s Kennedy Space Center in Florida. The company’s Falcon 9 rocket lifted off from Launch Complex 39A at 8:44 p.m. EDT, beginning SpaceX’s 25th resupply services mission to the orbiting laboratory.
Dragon is now safely in orbit with its solar arrays deployed and drawing power for the nearly two-day trip to the space station.
“We’re excited to continue to help transport this kind of cargo for NASA and also to carry the crew members who are the key component for doing research and managing things on station,” said Benjamin Reed, senior director of Human Spaceflight Programs at SpaceX. “All of this, of course, is not possible without our partnerships with NASA, with the Space Force, and all of our customers. We can’t thank you enough for the opportunity to be a part of this and be a part of this great science community.”
The spacecraft is scheduled to arrive at the space station on Saturday, July 16. Upon its arrival, Dragon will autonomously dock to the station’s Harmony module while NASA astronauts Jessica Watkins and Bob Hines monitor operations. Live coverage of Dragon’s arrival will air on NASA Television, the NASA app, and the agency’s website beginning at 10 a.m. EDT. Docking is scheduled for approximately 11:20 a.m.
In addition to delivering station supplies and hardware, Dragon also will deliver multiple science and research investigations. One of those is the Earth Surface Mineral Dust Source Investigation (EMIT). Developed by NASA’s Jet Propulsion Laboratory in California, EMIT will use imaging spectroscopy technology to measure the mineral composition of dust in Earth’s arid regions to better understand what effects it has on the planet.
The spacecraft also will deliver five CubeSats, or small satellites, with varying focuses of study; an investigation using tissue chips to study the aging of immune cells; and an experiment looking at an alternative for concrete using organic material and on-site materials. These are just a few of the more than 250 investigations that will take place during Expedition 67.
“It’s going to be a very busy next few weeks onboard the International Space Station with all the experiments and cargo that Dragon is bringing up,” said Dina Contella, operations integration manager for NASA’s International Space Station Program. “I just really want to congratulate again the SpaceX and NASA teams on another great launch, and I’m looking forward to the Dragon docking on Saturday.”
Dragon will spend about a month attached to the space station before autonomously undocking and returning to Earth with research and return cargo, splashing down in the Atlantic Ocean.
