SpaceX revealed a new business segment called Starshield aimed at U.S. national security government agencies. “While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on three areas: Earth observation, communications and hosted payloads,” the company said on its website.

This is a big deal as SpaceX is currently burning through $2 billion/year as it works to develop Starlink and Starship. So SpaceX wouldn’t mind some extra cash!

WASHINGTON — SpaceX on Dec. 2 revealed a new business segment called Starshield aimed at U.S. national security government agencies.

After the successful completion of India’s first space mission, homegrown firms are now looking to set up manufacturing facilities for satellites etc. Homegrown space startups, Pixxel and Dhruva Space, are eyeing new assembly facilities for satellite manufacturing in the country, following successful satellite launch missions on November 26.

Satellite manufacturing is an integral part of India’s plans for the space sector. The government’s liberalized space policy, which is said to be in the final stages of completion, is expected to allow the country’s firms to take a larger share of the global space market. At present, India accounts for only 2% of the global space economy, according to data shared by Jitendra Singh, Minister of State (MoS) for science, technology and earth sciences, in the Lok Sabha in August.

The two companies are also part of a growing crop of homegrown private space startups that are launching the final trial phase of their products and services. On November 18, Hyderabad-based Skyroot Aerospace became India’s first private firm to launch its own rocket. Pixxel and Dhruva’s satellites were successfully deployed in their intended low-earth orbits (LEOs) on November 26. India’s upcoming space policy is expected to invite more participation from such startups, taking some of the load off ISRO and its coffers.

The Federal Communications Commission issued a key authorization to Elon Musk’s SpaceX on Thursday to launch up to 7,500 next-generation satellites in its Starlink internet network.

“Specifically, we grant SpaceX authority to construct, deploy, and operate up to 7,500 satellites operating at altitudes of 525,530, and 535 km and inclinations of 53, 43, and 33 degrees, respectively, using frequencies in the Ku-and Ka-band. We defer consideration of SpaceX’s proposed use of E-band frequencies and tracking beacons,” said the order.

A small satellite developed by MIT engineers has set a new record for data transmission between a satellite and Earth. The TeraByte InfraRed Delivery (TBIRD) system used a laser to beam huge amounts of data at up to 100 gigabits per second (Gbps).

This data transmission speed is far greater than most connections you’ll get between the sky and the ground. SpaceX’s Starlink satellite internet offers up to 500 Mbps to Premium customers, and even the International Space Station’s data transmission tops out around 600 Mbps. That makes TBIRD up to 200 times faster.

The key difference is that most satellites communicate with ground stations via radio waves. TBIRD, on the other hand, uses laser light, which can carry up to 1,000 times more data in each transmission. Lasers come with their own hurdles though – the beams are much narrower, requiring more precise alignment between transmitter and receiver. And the light can be distorted by the atmosphere, leading to data loss. So TBIRD was designed to overcome these issues.

It will take 1.5 years to reach its final destination far beyond the moon.

In a world first, Japan’s space agency announced it successfully used steam to propel a spacecraft toward the Moon. Japan Aerospace Exploration Agency’s (JAXA) water-powered CubeSat spacecraft, EQUilibriUm Lunar-Earth point 6U (EQUULEUS), was launched on its way by NASA’s Orion spacecraft, which recently broke a record for the farthest distance traveled by a human-rated spacecraft.

“This is the world’s first successful orbit control beyond low-Earth orbit using water propellant propulsion system,” JAXA said in a statement on Saturday.

Plenty of potential solutions have been put forward to deal with the problem, but they all face a similar problem at the first step: how to track the debris they’re attempting to eliminate. Enter a new idea from researchers in Iran — using a novel type of radar to detect and track space debris before it becomes a danger.

The novel type of radar is called inverse synthetic aperture radar, or ISAR. As one might expect from the name, it’s the opposite of synthetic aperture radar (SAR). SAR has become much more prominent lately, especially by satellites attempting to collect data about the Earth, especially terrain data that might be useful for geospatial mapping.

The agency’s sent a tiny lunar lander aboard NASA’s Artemis I moon mission.

Japan will have to wait a little longer to perform its historic first lunar landing. That’s because a tiny Japanese moon lander that hitched a ride aboard NASA’s Artemis I moon mission has failed to make it to the lunar surface, a report from Space.com reveals.

Officials working on the OMOTENASHI moon spacecraft announced on Twitter that they had failed to pick up the CubeSat’s signal ahead of a planned lunar landing attempt.

SpaceX sent one of its first-stage boosters skyward for the 11th time on Tuesday evening. However, unlike its 10 previous flights, this time it didn’t return.

The mission launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida at 9:57 p.m. ET, lighting up the night sky as the Falcon 9 rocket roared toward space.

Thirty-five minutes after leaving the launchpad, the Falcon 9’s second stage deployed a communications satellite to a geosynchronous transfer orbit for French satellite operator Eutelsat.

A SpaceX recovery ship is headed more than a thousand kilometers downrange to support the second expendable Falcon 9 rocket launch in nine days.

No earlier than (NET) 9:57 pm EST (02:57 UTC) on Monday, November 21st, a Falcon 9 rocket is scheduled to lift off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad carrying the Eutelsat 10B geostationary communications satellite. For unknown reasons, the French communications provider paid extra to get as much performance as possible out of Falcon 9, requiring SpaceX to expend the rocket’s booster instead of attempting to land and reuse it.

The mission will be Eutelsat’s third Falcon 9 launch in less than three weeks and will wrap up a trio of launch contracts the company secretly signed with SpaceX to move satellites off of competitor Ariane Group’s unavailable Ariane 5 and delayed Ariane 6 rockets. In a rare coincidence, Eutelsat 10B will also be SpaceX’s second expendable Falcon 9 launch in a row and the third Falcon launch to expend a booster this month. But like those two other missions, not all of the Falcon rocket tasked with launching Eutelsat 10B will be lost.
