Crew Dragon Exploded Back in April Because of a Nitrogen Tetroxide Leak

On Saturday, April 20th, 2019, an explosion took place on SpaceX’s Landing Zone 1 at Cape Canaveral Air Force Station in Florida. The company was engaged in a series of static fire engine tests for their Crew Dragon‘s In-Flight Abort test vehicle. This vehicle is essential for crewed missions since it acts as a sort of ejection seat for the crew capsule in the event of an emergency.

While the initial tests of the twelve Draco thrusters on the vehicle were completed successfully, the initiation of the final test of eight SuperDraco thrusters resulted in the destruction of the vehicle. After a thorough investigation, SpaceX has concluded that the explosion was caused by a nitrogen tetroxide leak that occurred just prior to the final test.

Back in April 2019 Amazon signaled its intention to get into the internet satellite business. Following in the footsteps of SpaceX and their Starlink satellite system, Amazon intends to launch thousands of internet satellites in the coming years. Now that they’ve filed their application with the FCC, we have more details of their plan.

Virgin Orbit Tests its Satellite-Delivery Rocket for the First Time

Since 2015, Virgin Orbit has been developing a launch system that will send satellites into space using a rocket launched from a modified 747. This is part of Sir Richard Branson’s plan to crack the burgeoning market of cost-effective satellite deployment. This market is especially lucrative considering how many satellites are expected to be launched into orbit in the coming years.

This week, the Virgin Orbit team achieved a major milestone by flying the LauncherOne rocket into the air and releasing it over the Mojave desert for the first time. This drop-test not only validated the design of the modified 747 (named Cosmic Girl) that serves as its flying launchpad, it also demonstrated the effectiveness of the launch system – which can rely on regular airstrips instead of launch pads to send satellites into space.

SpaceX has Lost Contact With 3 of its Starlink Satellites

Back in May 23rd, 2019, SpaceX launched the first batch of its Starlink constellation, a fleet of satellites that will fulfill Elon Musk’s promise to provide broadband satellite-internet access to the entire planet. The deployment of these sixty satellites was the first in a series of six planned launches that would see around 720 satellites orbiting at an operational altitude of 550 km (340 mi).

Over the course of the past month, SpaceX announced that all sixty of the satellites were responsive, but recently indicated that contact had been lost with three of them. According to a statement issued by a company spokesperson on June 28th, these three satellites pose no danger as they will deorbit “passively” and burn up in the atmosphere.

Robotic asteroid mining spacecraft wins a grant from NASA

Back in April, NASA once again put out the call for proposals for the next generation of robotic explorers and missions. As part of the NASA Innovative Advanced Concepts (NIAC) Program, this consisted of researchers, scientists, and entrepreneurs coming together to submit early studies of new concepts that could one-day help advance NASA’s space exploration goals.

One concept that was selected for Phase III of development was a breakthrough mission and flight system called Mini Bee. This small, robotic mining craft was designed by the Trans Astronautica (TransAstra) Corporation to assist with deep-space missions. It is hoped that by leveraging this flight system architecture, the Mini-bee will enable the full-scale industrialization of space as well as human settlement.

Sen has Launched a 4K Video Stream to Space

In 2014, British entrepreneur Charles Black founded the company Sen (an acronym for Space Exploration Network) with the vision of “democratizing space”. Behind this vision was Black’s desire to create the world’s first 4K video streaming platform that could send video from space to billions of people worldwide. The purpose of this is to educate the public on our ever-changing world and our growing presence in space.

The key to this ambitious goal is the creation of a constellation of small satellites that will provide real-time video from Low Earth Orbit (LEO). The company recently took a major step towards making that happen by using their recently-deployed satellite to gather footage of Earth and space from orbit. This effectively demonstrated the capabilities of their platform and may represent a new step in NewSpace.

SpaceX just launched 60 satellites for its Starlink Constellation. Internet service providers should be very worried.

On Thursday, May 23rd, 2019, SpaceX launched the first batch of their Starlink satellites to orbit. The launch took place at 10:30 pm EDT (07:30 pm PDT) from Space Launch Complex 40 (SLC-40) at Cape Canaveral on the Florida coast. With this delivery, SpaceX founder Elon Musk is making good on his promise to begin providing global broadband internet access to the entire world, a goal that has become somewhat challenging in recent years.

Most of the Solar System Should be a Protected Wilderness. One-Eighth Left for Mining and Resource Exploitation

There is no doubt that our world is in the midst of a climate crisis. Between increasing levels of carbon dioxide in our atmosphere, rising temperatures and sea levels, ocean acidification, species extinctions, waste production, diminishing supplies of fresh water, drought, severe weather, and all of the resulting fallout, the “Anthropocene” is not shaping up too well.

It is little wonder then why luminaries like Stephen Hawking, Buzz Aldrin, and Elon Musk believe that we must look off-world to ensure our survival. However, there are those who caution that in so doing, humans will simply shift our burdens onto new locations. Addressing this possibility, two distinguished researchers recently published a paper where they suggest that we should set aside “wilderness” spaces” in our Solar System today.

The World’s Biggest Aircraft – the Rocket-Launching Stratolaunch – Completes its First Test Flight

In 2011, Microsoft co-founder Paul G. Allen and Scaled Composites founder Burt Rutan announced the creation of Stratolaunch Systems. With the goal of reducing the associated costs of space launches, the company set out to create the world’s largest air-launch-to-orbit system. After many years, these efforts bore fruit with the unveiling of the massive Scaled Composites Model 351 Stratolaunch air carrier in the Summer of 2017.

Similar in principle to Virgin Galactic’s SpaceShipTwo, this behemoth is designed to deploy rockets from high altitudes so they can send payloads to Low-Earth Orbit (LEO). After multiple tests involving engine preburns and taxiing on the runway, the aircraft made its inaugural flight last weekend (Saturday, April 13th) and flew for two and half hours before safely landing again in the Mojave Desert.

SpaceX Does it Again with Second Retrieval of Falcon Heavy Rocket

SpaceX has made some amazing accomplishments in the past few years, all of which have been in keeping with Elon Musk’s promise to cut the costs of space exploration. And with all the excitement surrounding the Starship Hopper and its first hop tests, there was one very important accomplishment that seems to have faded into the background a little.

Luckily, SpaceX reminded everyone about it this week, as the company conducted the second successful launch of their Falcon Heavy rocket from NASA’s Kennedy Space Center. But what was especially impressive this time around is the fact that they managed to retrieve all three of the Falcon Heavy’s rocket boosters, as well as the payload fairings.
