Scientists hope the world’s smallest satellites will boldly go where no probe has gone before.

During an interview at a Boston- area café, Zac Manchester apologized for not bringing along a copy of his latest satellite — one of many duplicates due to enter orbit this fall during a mission to the International Space Station. “Don’t worry,” says Manchester, a Stanford University professor of aeronautics and astronautics. “I’ll put one in an envelope and mail it to you.”
This discovery not only opened up an exciting new field of research, but has opened the door to many intriguing possibilities. One such possibility, according to a new study by a team of Russian scientists, is that gravitational waves could be used to transmit information. In much the same way as electromagnetic waves are used to communicate via antennas and satellites, the future of communications could be gravitationally-based.
The study, which recently appeared in the scientific journal Classical and Quantum Gravity, was led by Olga Babourova, a professor at the Moscow Pedagogical State University (MPSU), and included members from Moscow Automobile and Road Construction State Technical University (MADI) and the Peoples’ Friendship University of Russia (RUDN).
For the first time, astronomers have discovered what could be an exomoon, a moon outside our solar system. The exomoon was found around the gas giant exoplanet Kepler-1625b, which orbits a star 8,000 light-years from Earth.
Although moons are common in our solar system, which has nearly 200 natural satellites, the long search for interstellar moons has been an empty one. Astronomers have had success locating exoplanets around stars outside our solar system, but exomoons are harder to pinpoint because of their smaller size.
WASHINGTON — A Swedish company with plans for a geostationary communications satellite announced Oct. 16 a contract with SpaceX for a Falcon Heavy launch no earlier than the fourth quarter of 2020.
Ovzon of Solna, Sweden, has not yet purchased the satellite, but paid Eutelsat $1.6 million earlier this year to move one of its satellites to an unspecified Ovzon orbital slot to preserve spectrum rights at that location.
In a statement, Ovzon CEO Per Wahlberg said procurement of the company’s first satellite is “in the final stage,” and that production of an advanced onboard processor started earlier this month.
Speaking in a Satellite Innovation 2018 keynote, long-time SpaceX investor and board member Steve Jurvetson made a quiet but significant comment about the company’s Starlink satellite constellation efforts, stating that the first two prototype spacecraft – currently in orbit – “are working wonderfully.”
Standing in contrast to recent speculation that SpaceX’s Starlink project had experienced major failures with on-orbit hardware, Jurvetson may be a biased source but still has a major vested interest in SpaceX’s long-term success – supporting billions dumped into a satellite constellation with no real returns in sight would serve to seriously harm his significant investments in the company.
He would say that? Maybe, but @dfjsteve Jurvetson, early @SpaceX & @planet investor, told Satellite Innovation conference Oct 10, regarding SpaceX’s two Starlink test sats launched in February: pic.twitter.com/WHzJlPUEPA
This technology may someday power spacecraft, satellites, high-flying drones, and pacemakers.
SpaceX’s Falcon 9 is impressive, but based on launch photos it can be hard to get a sense of the true scale of the craft. On Wednesday, CEO Elon Musk shared an image that shows himself alongside three figures, standing next to a freshly-landed Falcon 9. The image gives a clear indication of how the craft appears in real life.
Musk shared the image below with the caption “At Falcon LZ-1 Vandenberg on Sunday night with the Base Commander. Support of [United States Air Force] much appreciated.” The image was taken just after Sunday’s launch, which saw the SAOCOM 1A satellite sent up from the Vandenberg Air Force Base, before the first stage booster landed on the firm’s brand new west coast landing pad. The whole craft measures 229.6 feet tall, with a 12-foot diameter. The composite fairing, which houses the satellite entering orbit, measures 43 feet with a 17-foot diameter.

Spotted on an official SpaceX T-shirt commemorating Starlink’s first two prototype satellites and corroborated through analysis of limited public photos of the spacecraft, SpaceX appears to be testing a relatively unique style of solar arrays on the first two satellites launched into orbit, known as Tintin A (Alice) and B (Bob).
It’s difficult to judge anything concrete from the nature of what may be immature prototypes, but SpaceX’s decision to take a major step away from its own style of solar expertise – Cargo Dragon’s traditional rigid panel arrays – is almost certainly motivated by a need to push beyond the current state of the art of satellite design and production.
According to NASASpaceflight.com, SpaceX has finished painting a fresh “X” on their newest Falcon 9 landing zone, located just a quarter of a mile from the company’s SLC-4 Vandenberg Air Force Base launch facilities.
In work in one shape or another since late 2014, mainly due to a lack of a pressing need for the pad, it’s looking increasingly likely that the West Coast landing zone (LZ) will be used for the first time on October 6th, shortly after a flight-proven Falcon 9 Block 5 rocket launches the Argentinian Earth-sensing satellite SAOCOM-1A.
SpaceX Falcon 9 launch with SAOCOM 1A coming up at Vandenberg next weekend. Static Fire test is NET October 2.
