The Recent Parachute Tests of SpaceX Did Not Meet Up With Expectations

NASA is quite desperate for their own solution on transporting astronauts to and from the International Space Station. They have paid both SpaceX as well as Boeing huge sums of money to figure out exactly how it can be done. Both the organizations have missed their projected targets on a consistent basis as far as manned spaceflight is concerned. SpaceX has been successful in completing a trip to the ISS with their Crew Dragon.

SpaceX seems to be the leader in this, which has come as a surprise for a number of observers. Boeing, it seems, has a truly endless amount of resources at their disposal. Still, they are yet to launch their Starliner spacecraft. A recent hearing of a House subcommittee clearly revealed that a misstep from SpaceX might well have opened the door for Boeing to step in and become a winner in the race towards crewed missions in space. William Gerstenmaier of NASA, at the time of the hearing, revealed that a parachute system test could not live up to the expectations. It was a failure. Gerstenmaier further said that the parachutes did not work as they were designed.

Under the normal conditions of operation, a series of four parachutes would get deployed in a simultaneous manner. This tends to ease out the descent and allow the capsule to have a comfortable touchdown. Still, NASA has to stay prepared for any and all kinds of circumstances. This is why the parachute system was tested with only three of their four parachutes deployed. Hence it managed to simulate a failure of a single parachute. It was really unfortunate that the three parachutes did not work as it was intended and also failed to reduce the speed of this test vehicle, for the landing to take place safely.

Congress Is Not Pleased That NASA Still Does Not Have Any Plan for Moon

Congress Is Not Pleased That NASA Still Does Not Have Any Plan for Moon

It was back in the month of August when the Trump Administration had instructed NASA to put an astronaut on the surface of the Moon. They had told them to do so by the year 2024. As per NASA’s planning, their target was to achieve the goal by the year 2028. Now, this acceleration of time managed to put NASA in an unexpected state of nervousness. The time to achieve the target four years closer than normal meant that the space agency needed to quickly find a way out to cut down four years from their plans and thus accelerate their progress in work.

According to media reports, the acceleration that is required on the part of NASA to meet the target within 2024 has not been going well. It clearly suggests that the acceleration of the timeline might well have been a lot more ambitious in nature. NASA has not yet delivered the budget proposal, which the Congress had asked them to deliver by the month of March. Due to this delay, the federal representatives are seeking answers from the agency. The administrator of NASA, Bill Gerstenmaier talked about the missed deadline of presenting the budget. He said that the budget was not yet ready during the hearing with the House of Representatives Committee on Science, Space, and Technology on Wednesday.

Finally, Bill Gerstenmaier said that he had expected it to be quite a number of weeks more before NASA could sort out their budget. A representative from Oklahoma, Kendra Horn said at the time of hearing that the acceleration of four years had left NASA totally puzzled to develop a plan and hasten to pull together a budget amendment, which has still not got delivered.

The Dragon Cargo Spacecraft Gets Caught Up By Giant Robotic Arm

The Dragon Cargo Spacecraft Gets Caught Up By Giant Robotic Arm

The crew members on the International Space Station had caught and installed the Dragon cargo of SpaceX on Monday morning. They all helped in controlling a huge robotic arm to catch hold of the spacecraft, which was carrying 5500 pounds of research, hardware, and supplies for the crew. Astronauts on the International Space Station had captured the Dragon cargo ship with the robotic arm at 7:01 am EDT. At that time, both spacecraft had sailed 254 miles above the North Atlantic Ocean.

Saint-Jacques said that as a Canadian, he felt extremely proud every time they get to use Canadarm2 for capturing the free-flyer. They basically represented the dedicated teams of talented people who make what seems to be impossible, a reality every single day. By the time, 9:32 am EDT, flight controllers on Earth had made use of the robotic arm of the station to get Dragon attached to a berth that was available on the station. This allowed the astronauts to start unloading supplies. SpaceX had launched the Dragon cargo ship early on Saturday on top of a Falcon 9 rocket from the Cape Canaveral Air Force Station in Florida after more than a week’s delay.

The current delivery mission of Dragon is known as CRS-17 by NASA and SpaceX-17 by the company. SpaceX is also in the process of developing a crewed version of the Dragon spacecraft. The company had launched their first Crew Dragon capsule test flight earlier in the year. They hope to start off with their astronaut flights by the end of this year. It is important for SpaceX to complete the investigation into why their Crew Dragon spacecraft had exploded at the time of a ground test of their emergency abort system last month. Only after this can those crewed flights start off.

Space Station Issue Leads To the Delay in Launching Resupply of SpaceX

Space Station Issue Leads To the Delay in Launching Resupply of SpaceX

A supply ship of SpaceX Dragon, stuffed with almost three tons of experiments, provisions for the crews and supplies would stay on the ground until Friday morning. They will stay there to provide more time for the controllers of NASA flight to rectify a problem related to an electrical distribution unit on the International Space Station. Engineers had detected a problem with the Main Bus Switching Unit on Monday morning. The ground teams might elect to get the component replaced later in this week before the cargo launch of SpaceX.

The Main Bus Switching Unit happens to be one of the many that give proper route to the power for the US solar arrays of the space station to electrical channels of the research outpost. The suspect unit distributes power to two out of the eight electrical channels on the station. This includes a power supply for the robotic arms of the space station. The station astronauts will use the robotic arm in order to get hold of the Dragon cargo craft, while it approaches the complex. The robotic arms stay powered by way of a separate channel, while the flight rules of NASA need redundant supplies of power for the arm to carry out critical operations.

On Monday, the officials said that engineers were carefully looking into an unspecified problem with a Main Bus Switching Unit. NASA said that managers discussed how can the problem related to power system impact the plans for launching the SpaceX resupply. In case the Dragon spacecraft was to launch on Wednesday, the due time for its arrival at the station would have been early Saturday. If the launch from Cape Canaveral will be on Friday morning, then the Dragon cargo should come to the complex early Sunday.

A Famous Theory of Black Holes Has Suffered A Huge Setback

A Famous Theory of Black Holes Has Suffered A Huge Setback

There have been numerous theories related to the dark matter of our universe, which Stephen Hawking had come up with. Now, one of his most famous theories related to the black hole has recently suffered a big blow. This is concluded from a huge telescope that managed to capture an image of the whole galaxy through one shot. The findings do not completely rule out the famous idea of Stephen Hawking. Still, they suggest that the primordial black holes would need to be extremely small to explain the dark matter.

Back in the 1970s, great Physicist, Stephen Hawking along with his colleagues came up with the theory that the Big Bang might well have created a large number of somewhat small black holes. All these really small, ancient black holes would be extremely difficult to see but still manage to exert a big gravitational pull on other objects. Black holes do not emit light, though the huge ones get fringed by some bright disks of a hot matter. Masahiro Takada along with his team managed to take around 200 pictures of the Andromeda Galaxy for more than 7 hours on a clear night sky. They only found out one possible microlensing event. According to them, if primordial black holes did makeup quite a significant fraction of dark matter, they must have noticed around 1000 microlensing signals.

Takada and his team had come across one single flash in their survey. Though it was one, preliminary result, still this could well end up to be extremely important. The first ever detection of a primordial black hole could be quite a groundbreaking validation of some of the work put in by Hawking. Still, Takada feels that a single observation is not too convincing. There is a need for more observations to confirm.
