NASA Ends MAVEN Mission After Six-Month Fight to Restore Contact
NASA has officially concluded the MAVEN (Mars Atmosphere and Volatile Evolution) mission following a six-month attempt to regain communications with the spacecraft. Before the mission ended, scientists extracted enough data to identify a previously undocumented atmospheric phenomenon at Mars.
MAVEN launched in 2013 and had been studying how Mars lost its atmosphere over time. Losing contact and then spending six months trying to recover it before pulling the plug is an unusual end for a flagship planetary science mission. No replacement mission for this atmospheric monitoring role is currently announced.

Falcon 9 Booster Flies Record 35th Mission on Starlink 10-35
A Falcon 9 first stage flew its 35th flight on the Starlink 10-35 mission, the highest reuse count for any orbital booster. Liftoff was from LC-40 at Cape Canaveral Space Force Station during a window opening at 6:07 a.m. EDT.
Starlink 10-35 is the 53rd dedicated Starlink Group 10 launch. Each new batch adds to the growing catalog of active Starlink satellites trackable in KeepTrack’s real-time satellite browser.

NASA Open to Hubble Reboost If Operating Costs Drop
NASA says it would consider a reboost mission for Hubble, which is in a slowly decaying orbit, but only if the telescope’s operating costs can be reduced first. The agency is currently preparing a reboost attempt for a separate astronomy spacecraft in a similar situation.
Hubble currently orbits at roughly 540 km. Without intervention, atmospheric drag will bring it down over the coming decades. Track Hubble to monitor its current orbital altitude and decay trend.

UK’s NewOrbit Raises $18.5M to Build VLEO Satellites
NewOrbit Space closed an $18.5 million Series A round to develop satellites for very low Earth orbit (VLEO), typically defined as below 450 km. The UK-based company is targeting a regime that offers improved resolution for Earth observation but demands active propulsion to counteract significantly higher atmospheric drag.
VLEO is getting more crowded on the investment side. NewOrbit joins a small group of companies — including Skeyeon and AtmosOne — explicitly targeting this altitude band as a product differentiator.

OQ Technology Plans Direct-to-Smartphone Demo in Germany Using Local Spectrum
Luxembourg-based OQ Technology plans to test satellite direct-to-smartphone connectivity in Germany using spectrum licensed to a German telecommunications operator. The demo is targeted for 2027.
The approach — using a local telco’s cellular spectrum rather than satellite-specific bands — is a direct challenge to how AST SpaceMobile and Starlink have structured their direct-to-cell services. Regulatory access to cellular spectrum varies sharply by country, which makes this a replicable model in markets where U.S.-led services face licensing friction.

NASA to Pick New Washington-Area Headquarters by End of 2026
NASA plans to select a new headquarters building before the end of this year. The agency is staying in the Washington area but moving out of its current Two Independence Square location.
The relocation is an administrative move, but the timeline adds to an already busy period of organizational pressure at NASA, including ongoing budget uncertainty and workforce reductions under the current administration.

Large Magellanic Cloud Is Tidally Disrupting the Small Magellanic Cloud
New research confirms the Large Magellanic Cloud is actively stripping material from its smaller companion, the Small Magellanic Cloud, through tidal forces. Both galaxies are making what is likely their first close pass by the Milky Way.
The two have been gravitationally interacting with each other for billions of years despite that first-pass status relative to our galaxy. The observed disruption is helping astronomers model how dwarf galaxy interactions evolve before a larger galactic merger.

Satellite of the Day
TYSK Satellite (NORAD 57581)
Launched on August 10, 2023, from the Jiuquan Satellite Center aboard a Gushenxing 1 vehicle, this Chinese satellite was designed and manufactured by WEINA. The spacecraft features a box-shaped body with two solar panels and had a launch mass of 35 kilograms, making it a compact payload in China’s expanding satellite constellation. Despite its relatively recent launch, this satellite has since decayed from orbit, marking the end of its operational mission.
The satellite was placed into a sun-synchronous orbit with a 97.419° inclination, ideal for Earth observation and remote sensing applications common to many contemporary small satellite programs. While the specific mission details remain limited in open sources, its orbital characteristics suggest it was designed for persistent observation capabilities. This mission represents part of China’s broader effort to build a comprehensive space-based monitoring infrastructure using distributed small satellite networks.
