Alice Maria it's increasingly difficult to keep it to just five stories every day, so we have three additional links in today's Selected Reading section for you to read up on. Aerospace Lab in partnership with Mitsui Bussun Aerospace has been selected by the Japan Exploration Agency to supply the platform that will host JAXA's SAMURAI payload as part of a demonstration mission. A US researcher says he won't receive NASA funding to study a Chinese lunar sample, and RAFT has been awarded another space force, OTA for secure data transformations.

It's Friday, so that can only mean one thing. Here on T Minus, our partners at NSF have the Space Traffic Report.

Ryan Catey (9:37)

I'm Ryan Catey for NSF and this is your weekly Space Traffic Report for T Minus Space. Kicking off the week, we had the launch of a Chungzhong 3B from Xichang on April 27 at 15:54 UTC. The mission was carrying the fifth Tianlian 2 Communications Relay Satellite into geosynchronous transfer orbit. These satellites are akin to NASA's TDRS constellation, which allows ground teams communicate with spacecraft and satellites even without direct line of sight with a ground station. This week we also had a myriad of launchers carrying Internet satellites into space the first started from Florida on April 28th at 0209 Universal Time. That was with a Falcon 9 rocket carrying a mixed batch of Starlink V2 mini and direct to cell satellites into orbit. The first stage for this mission was a veteran flying for a 20th time and it successfully landed on SpaceX's drone ship. Just read the instructions. By the way, this mission marked the 250th dedicated flight for the Starlink Constellation back in China. A Changzhong 5B lifted off from Wenchang on April 28 at 20:10 UTC, carrying 10 Guo Wang Internet satellites into a polar low earth orbit. This rocket is infamous for leaving its core stage in an uncontrollable orbit, but for this mission it carried a Yuanjiang two kick stage, which meant no 20 ton core stages in orbit this time around. A sigh of relief from Spanish Air traffic control. Just minutes after that launch at 2042 UT, another Falcon 9 took off from Vandenberg carrying 27 V2 mini satellites into low earth orbit. This mission saw the oldest Falcon 9 booster in the fleet, B1063, launching and landing for a 25th time, becoming the second booster to reach 25 flights moving east to Florida. We then had an Atlas V lifting off from space launch complex421 the same day at 2301 UTC. For this mission, Atlas was carrying a batch of 27 Kuiper satellites for Amazon's Project Kuiper. After quite the delay to get them off the ground, Amazon finally has its first batch of operational KUIP satellites in orbit. You may remember Atlas had already flown two prototype satellites back in 2023, but since then it's been radio silence from Amazon on when they would launch the operational batches. For that matter, we still haven't actually seen the satellites onboard the rocket and the official UAA feed ended just after booster engine cutoff. The company has a pretty busy schedule coming up if they want to keep their licensing rights with the Federal Communications Commission as it needs to launch half of the over 3000 satellite const. Needless to say, they're probably going to need a push to the right on that deadline. And just a few hours later, from Neighbouring Launch Complex 39A, another Falcon 9 took off on April 29th at 0234 UTC. It was carrying a mixed batch of Starlink direct to cell and Starlink V2 mini satellites into low earth orbit. However, this wasn't your ordinary Starlink launch as it was debuting a new booster with serial number B1094. Despite being new, it definitely had read the instructions because it successfully landed on SpaceX's drone ship, a shortfall of gravitas and I' see it flying again very soon. If you were keeping track of all the times and launches, that was 110 satellites for three different Internet satellite constellations launched within 25 hours. I'm sure friend of the show and astronomer Jonathan McDowell will be very busy tracking all of them. The launch frenzy didn't end there though, as we had a Vega C launching from the Guiana space Center on April 29th at 0915 UTC. The mission was carrying the Biomass Earth Observation Satellite into a sun synchronous orbit for the European Space Agency. Biomass is set to use a large deployable radar antenna to perform synthetic aperture radar observations of Earth's forests. This will give the scientists on Earth further insights into how much carbon they store and how it evolves over several seasons. ESA also intends to use this antenna to look at other places on Earth, like deserts and glaciers, and gather more data on how those also evolve over time. And to wrap up the launches in April, we unfortunately had the launch failure of Firefly's Alpha rocket. Liftoff of the rocket's sixth flight, nicknamed Message in Abusa, took place on April 29 at 13:37 UTC from Space Launch Complex 2 West in Vandenberg. The rocket was carrying a prototype satellite from Lockheed Martin using Lockheed's latest LM400 satellite bus. The ascent phase of flight for Alpha looked pretty much like all of the previous successful missions in the past. However, after main engine cutoff, a large cloud could be seen from where the rocket was supposed to be, and a few seconds later onboard footage showed chunks of hardware flying off. Furthermore, it looked like the nozzle extension lightning engine of Alpha's upper stage was completely missing. After a bit of a wobble from the visibly violent stage separation event, it looked as if everything was fine, but the big question was whether Alpha would have enough performance to reach orbit with this payload or not. As it turned out, Firefly announced after the mission that indeed it was not enough performance and the rocket and payload did not reach orbit and fell into the Pacific Ocean. With this failure, Alpha currently stands at only two fully successful flights out of its six total. However, the guidance and navigation showed that the second stage is pretty resilient matter what you can throw at it. That Alpha launch was also the 26th and last launch of April, bringing to a close the most active April in space history. In the ranking of space launches, the US remains at the top thanks to SpaceX, which as of the end of the month had launched 50 Falcon 9 rockets. Barring any surprises, it looks like we'll have more than 280 launches worldwide by the end of the year. And who knows, Maybe we'll cross 300 launches for the first time at the end of the month. We also have the return of the Shenzhou 19 crew from the Tiangong Space Station following last week's arrival of the Crew of Shenzhou 20. The spacecraft undocked from the station's forward docking port on April 29th at 20:00 UTC to start its journey back home. On board were Commander Hai Ju Cha and flight engineers Songling Dong and Wang Haotza. Following a one day delay due to wind conditions at the original landing site, Shenzhou 19's descent capsule touched down on the desert plains of the eastern Inner mongolia region on April 30th at 0508 UTC. During the crew's 182 day stay on the station, the trio performed dozens of science experiments and observations and conducted two spacewalks, one of them breaking the record for the longest spacewalk at over nine hours in duration. This was the second flight for Jucha, logging a total of nearly 365 days in space across two missions. Lingdong and Hiaotza were flying for the first time, so they now have logged those 182 days in space from this mission. Up in space, NASA astronauts Anne McLean and Nicole Ayers performed the 275th spacewalk in support of the ISS project. The five hour, 44 minute excursion started off on May 1 at 1305 Utah, during which the pair relocated a communications antenna and installed a mounting bracket for a future rollout solar array. McClane and Ayers also installed a jumper cable to carry power from the P6 truss located on the portmost side of the station out to the Russian side of the station. The spacewalk was preceded the day before by an unplanned reboost of the ISS by the Progress MS.30 spacecraft. This was performed due to a piece of debris from a Chungjung 6 rocket that launched in 2005 that could have come as close as 600 meters from the station had the maneuver not been performed. Thankfully, this didn't impact the spacewalk plans at all, and to wrap up the week we had another Starlink launch from Florida. Liftoff of Falcon 9 with 28 Starlink V2 mini satellites on board took place on May 2nd at 1:51 UTC. The booster for this mission was flying for an 18th time and it successfully landed on SpaceX's drone ship. Just read the instructions. With the many Starlink launches this week, SpaceX has now launched a total of 8,431 Starlink satellites, of which 1,097 have re entered and 6,500 have moved into their operational orbit. Before too long, we're going to have kuiperstats in here too. Going into next week, we have yet more Internet satellite launches, with potentially up to four Starlink launches from all three of Falcon 9's launch pads. China might also launch next week the second flight of the Changjung 12 rocket, this time carrying a batch of Guo Wang Internet satellites.

Welcome back. Imagine a camera so powerful it can snap a pic of every galaxy in the universe. No pressure, right? Well, NASA's Sphere X telescope is doing just that. It is mapping the entire sky in 102 infrared colors. And it has just started its science mission, Sphere X, which stands for Spectrophotometer for the History of the Universe, Epoch of Reionization, and ICES Explorer. Yes, please try saying that three times fast. Launched on March 11, and every day it's snapping about 3,600 images, creating a cosmic map like no other. So why does all this matter? Well, by observing an infrared wavelength, which is light invisible to our eyes, SphereX is peering into the universe's past, studying everything from the formation of galaxies to the search for life's building blocks in interstellar dust clouds. Over the next two years, SphereX will complete more than 11,000 orbits around the Earth, circling Earth about 14 and a half times a day and mapping the sky in every direction. It's like taking a panoramic photo of the cosmos. Every six months, JPL has released a video marking the start of the science mission. And by the way, it is gorgeous. It shows Spherex's field of view as it scans across one section of the sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths that the telescope's detectors see. The view from one detector array moves from purple to green, followed by the second array's view, which changes from yellow to red. And it's got us excited to see what Sphere X will release in the coming months and years when it gets further into its mission.
