By now, you’ve no doubt heard of (or seen) Starlink. SpaceX’s mega-satellite constellation has become a permanent fixture in our skies as of late, with several routine passes on any given week. But have you seen the supposed ‘black sheep’ of the flock, DarkSat?

SpaceX Crew Dragon Capsule Nails In-Flight Abort Test! Next Stop, the ISS!

At Launch Complex 39A at the Kennedy Space Center in Cape Canaveral, Florida, during the morning hours this past Sunday (Jan, 19th), SpaceX conducted the final uncrewed test of their Crew Dragon space capsule. This was the all-important in-flight abort test, the purpose of which was to validate the crew capsule’s escape capabilities in the event of an unexpected emergency during launch.

The event, which was live-streamed by NASA TV, was a complete success and saw the Crew Dragon successfully separate from its Falcon 9 launcher before being retrieved at sea. With this test complete, NASA and SpaceX will be moving forward with the first crewed mission. Known as Crew Demo-2, this mission will see two astronauts launched aboard the Crew Dragon to the International Space Station (ISS) later this year.

Scientists Figure Out How to Continuously Watch the Entire Planet With Just 4 Satellites

For decades, scientists have been trying to figure out the minimum number of satellites that would be able to see every point on Earth. This question is motivated in part by the growing problem of space debris, but also by considerations of cost and efficiency. By the mid-1980s, researcher John E. Draim proposed a solution to this problem in a series of studies, claiming that a four-satellite constellation was all that was needed.

Unfortunately, his solution simply wasn’t practical at the time since a tremendous amount of propellant would be needed to keep the satellites in orbit. But thanks to a recent collaborative study, a team of researchers has found the right combination of factors to make a four-satellite constellation possible. Their findings could drive advances in telecommunication, navigation, and remote sensing while also reducing costs.

Starship Mk 1 Blows its Top During Testing

SpaceX has been on a roll lately. With the completion of tethered and untethered flight tests with the Starship Hopper, SpaceX founder Elon Musk unveiled the newly-completed Starship Mk 1 prototype and announced that orbital test flights would commence in a few months. Meanwhile, the Starlink constellation got started with the launch of its first 60 satellites, followed by 60 more upgraded versions.

Unfortunately, there are always some speed bumps along the way. Yesterday, during a cryogenic loading test, the Starship Mk 1 experienced an explosion that sent its top bulkhead flying off and dispersing frozen vapor all over the launch area. However, SpaceX has indicated in an official statement that this setback was not unforeseen and won’t hamper the orbital flight test of the prototype for long.

SpaceX Launches Another 60 Starlink Satellites

In May of 2019, Elon Musk began delivering on his promise to create a constellation of satellites (named Starlink) that would offer broadband internet access. It all started with the launch of the first sixty Starlink satellites and was followed by Musk sending the inaugural tweet using the service this past October. Earlier today, another batch of Starlink satellites was sent into space as part of a live-streamed launch event.

The mission, known as Starlink-1, saw the launch of another 60 satellites from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida, atop a Falcon 9 rocket. Unlike previous launches, this mission involved the latest version of Starlink (Starlink 1.0), which feature a number of upgrades and refinements over the previous version (Starlink 0.9) and made this mission the heaviest Starlink launch to date.

SpaceX is Sure They’ll be Able to Land Starship on the Moon in 2022

Things are looking pretty good for Elon Musk and SpaceX, the company he founded back in 2002 with the intent of reinvigorating space exploration. In the last six months alone, SpaceX has deployed the first batch of its Starlink broadband internet satellites to space, conducted two successful untethered tests with the Starship Hopper, and finished work on the first orbital-class Starship test vehicle (the Mk.1).

And at the 70th International Astronautical Congress, which took place last week in Washington, DC, SpaceX president and Chief Operations Officer Gwynne Shotwell provided additional details about the Starship‘s mission timeline. As she indicated during a series of interviews, the company hopes to be sending the Starship to orbit next year, landing on the Moon by 2022, and sending payloads to the lunar surface by 2024.

In January of 2015, Elon Musk shared his vision of creating a constellation of satellites in Low Earth Orbit (LEO) that would provide broadband internet access to the entire planet. Back in May, SpaceX launched the first batch of 60 Starlink satellites to orbit, with plans to send an additional 1,584 to space by 2024 and 2,200 more by 2027.

Naturally, consumers have been wondering when they will be able to avail themselves of this new internet service. As SpaceX Chief Operations Officer Gwynne Shotwell announced on October 22nd, the company should be able to offer broadband access within the US by mid-2020. This came a day after Musk sent the inaugural tweet using Starlink services.

SpaceX Files a Request to Launch Another 30,000 Satellites for Starlink, on Top of the 12,000 They’re Already Planning to Launch

SpaceX is really kicking things into high-gear with its Starlink network. The creation of this satellite constellation is central to Elon Musk’s vision of providing high-bandwidth internet access to a global market. Deployment began in earnest back in May with the launch of the first sixty Starlink satellites, with plans to launch an additional 1,584 by 2024 and 2,200 by 2027.

Until now, SpaceX’s long-term goal was to create a constellation of 12,000 satellites at altitudes ranging from 328 km to 580 km (200 to 360 mi) – based on what the FCC has approved so far. But according to recent filings with the International Telecommunication Union (ITU), SpaceX intends to send an additional 30,000 Starlink satellites to Low Earth Orbit (LEO) in the coming years.
