WASHINGTON — SpaceX’s ambitious Starlink satellite network is exceeding expectations at a blistering pace, according to a new report by Quilty Space, a market research and consulting firm.
At about 1:30 am EST on Feb. 28, NASA’s Thermosphere Ionosphere Mesosphere Energetics and Dynamics Mission (TIMED) spacecraft passed close to a defunct Russian satellite, Cosmos 2221. The close approach was alarming enough that NASA sent reporters an email in the middle of the night, alerting them to the conjunction and a blog post about it. “Although the spacecraft are expected to miss each other, a collision could result in significant debris generation,” NASA warned.
WASHINGTON — NASA will seek “out of the box” ideas in a bid to reduce the costs and shorten the schedule for returning samples from Mars.
WASHINGTON — NASA is willing to consider proposals for revamping its Mars Sample Return program that would return as few as 10 sample tubes, a fraction of the number originally planned.
In late March, the Indian Space Research Organisation (ISRO) announced that one of its satellite missions “practically left zero debris in orbit” after a spent rocket stage was lowered to burn up in Earth’s atmosphere during re-entry.
Tremendous explosions in a galaxy close to the Milky Way are pouring material equivalent to around 50 million suns into its surroundings. Astronomers mapped this galactic pollution event in high resolution, obtaining important hints about how the space between galaxies becomes filled with chemical elements that eventually become the building blocks of new stars.
Multiple major coral reefs around the world are getting paler due to warming sea temperatures in the fourth-ever global bleaching event, and satellites are keeping tabs on the carnage.
NASA’s interstellar explorer Voyager 1 is finally communicating with ground control in an understandable way again. On Saturday (April 20), Voyager 1 updated ground control about its health status for the first time in 5 months. While the Voyager 1 spacecraft still isn’t sending valid science data back to Earth, it is now returning usable information about the health and operating status of its onboard engineering systems.
Three days before Christmas, an Alpha rocket built by Firefly Aerospace lifted off from Vandenberg Space Force Base in California. The initial phases of the flight appeared to go as expected, placing the upper stage and its satellite payload, a Lockheed Martin technology demonstration satellite called Tantrum, into a parking orbit. All that was left, Firefly said as it wrapped up its launch webcast, was a second burn of the upper stage about 40 minutes later to circularize the orbit.
