Maya Wiley Lands Main Endorsement From Rep. Hakeem Jeffries

Maya Wiley Lands Major Endorsement From Rep. Hakeem Jeffries

Ms. Wiley, one of the more left-wing candidates in the race, said she heard from Mr. Jeffries on Friday evening and added that he, along with Ms. Clarke and Ms. Velázquez, were “leaders whose voters trust them”. respect them and they move voices. “

“Letting Hakeem Jeffries stand up with me and say, ‘This is my candidate’ is of tremendous importance in an extremely important part of this city to win for anyone who wants to become mayor of New York City,” she added .

In the June primary, New Yorkers can rate up to five mayoral candidates, and Mr Jeffries said he may disclose other rankings of his choice for mayor, but said he has not yet made a decision on how to proceed.

In the interview, he outlined a detailed map of what he saw as Ms. Wiley’s path to victory, though with an overcrowded field of candidates there is certainly significant competition for every major political constituency in New York.

“I expect Eric Adams and Maya Wiley will perform best in the communities in central Brooklyn as well as in other traditionally African American neighborhoods in New York,” Jeffries said, noting Ms. Wiley’s potential in “both traditionally African American communities.” also in parts of the city where many white liberals live, with neighborhoods like Chelsea in Manhattan and progressive enclaves in Brooklyn being mentioned.

“It’s a pretty powerful option if the campaign can keep putting it together over the next few weeks,” he said.

Some rival Democrats have feared the prospect of a late surge in Ms. Wiley and the weeks ahead will test their ability to take advantage of that opportunity.

SpaceX lands Starship rocket SN15 after check flight

SpaceX lands Starship rocket SN15 after test flight

The Starship prototype SN15 missile lands on the company’s landing pad in Boca Chica, Texas on May 5, 2020.

SpaceX

Elon Musk’s SpaceX launched and landed the latest prototype of his Starship rocket on Wednesday in the fifth test flight at high altitude of the system.

The spaceship’s prototype rocket, serial number 15 or SN15, flew up to 10 kilometers, or approximately 33,000 feet.

“Spaceship is nominally landing!” Musk tweeted after landing. Nominal is a space industry term used to denote when things go according to plan.

SN15 was the first Starship prototype that was not destroyed after a test flight at high altitude. While a small fire broke out at the base of the rocket after landing, the fire appeared to be contained a few minutes later.

The company is developing Starship to bring cargo and people on missions to the moon and Mars.

Earlier this month, NASA placed an almost $ 3 billion contract with SpaceX to build a lunar variant of Starship to bring astronauts to the surface of the moon for the agency’s Artemis missions. While Musk’s company continued to advance Starship development, NASA stopped SpaceX work on the HLS program after Jeff Bezos ‘Blue Origin and Leidos’ subsidiary Dynetics each filed protests against NASA’s procurement.

The SN15 flight was similar to what SpaceX has conducted over the past six months with the test flights of the prototypes SN8, SN9, SN10 and SN11. While each of the previous missiles was successfully launched and several development goals were achieved, all four prototypes were explosively destroyed – SN8 and SN9 on impact during the landing attempts, SN10 a few minutes after landing and SN11 just before the landing attempt.

The Starship prototypes are about 150 feet tall, or about the size of a 15-story building, and are each powered by three Raptor rocket engines.

It’s made of stainless steel and is the early version of the rocket that Musk unveiled in 2019.

The Starship prototype SN15 rocket is on the company’s launch pad in Boca Chica, Texas.

SpaceX

SpaceX noted in a statement on its website that the SN15 has “vehicle enhancements in terms of structure, avionics and software” compared to previous Starship prototypes.

“Specifically, a new, improved avionics suite, an updated fuel architecture in the tail skirt, and a new design and configuration for Raptor engines,” said SpaceX.

The Federal Aviation Administration, which has an inspector at the SpaceX facilities to monitor the test flights, conducted a “breakdown” investigation of the SN11 flight.

Last week, the FAA announced the approval of the next three Starship launches – SN15, SN16, and SN16 – and said it would “verify that SpaceX has implemented corrective actions resulting from the SN11 breakdown investigation”.

The FAA approved multiple launches “because SpaceX makes few changes to the launcher and relies on the FAA-approved method to calculate the risk to the public.”

SpaceX lands Starship SN10 rocket after a high-altitude flight take a look at

SpaceX lands Starship SN10 rocket after a high-altitude flight test

The Starship prototype SN9 starts at the company’s development facility in Boca Chica, Texas.

SpaceX

SpaceX’s spaceship prototype exploded for the first time shortly after landing after a high-altitude flight test on Wednesday.

The cause of the explosion, or whether it was intentional, was not immediately clear.

The company test flew with the Starship rocket Serial Number 10 or SN10. SpaceX wanted to launch the prototype to an altitude of 10 kilometers or an altitude of 32,800 feet.

The Starship prototype stands about 150 feet tall, or about the size of a 15-story building, and is powered by three Raptor rocket engines. The rocket is made of stainless steel and represents the early versions of the rocket introduced in 2019.

Musk’s company develops Starship with the goal of bringing cargo and people on missions to the moon and Mars.

The SN10 flight was similar to SpaceX’s December and February when it tested the SN8 and SN9 prototypes. Both earlier missiles served multiple development goals – including testing aerodynamics, turning off the engines one at a time, and turning them around to align for landing – but both prototypes exploded on impact when attempting to land and couldn’t slow down enough.

As with the SN8 and SN9, the goal of the SN10 flight was not necessarily to reach the maximum altitude, but rather to test several important parts of the spacecraft system. SpaceX fired all three engines to take off, then shut them off one by one as the rocket neared its intended altitude.

SN10 then transferred propellant from the main tanks to the collection tanks before turning for the “belly flop” reentry maneuver – allowing it a controlled descent through the air with the missile’s four flaps. In the final moments of the descent, SpaceX turned the rocket over and brought it back into a vertical orientation. The Raptor engines were fired to slow down for landing.

Starship is one of two “Manhattan projects” that SpaceX is developing at the same time. The other is the Starlink satellite internet program. Musk previously estimated that Starship would cost around $ 5 billion to fully develop, although SpaceX has not yet disclosed how much it has spent on the program.

The company raised $ 850 million in its most recent capital raise, valued at $ 74 billion, last month.

Musk remains “very confident” that Starship “will be safe enough for human transportation by 2023” – an ambitious target as the company began serious development and testing of the missile in early 2019.

But Musk’s schedule is crucial, as Japanese billionaire Yusaku Maezawa has paid to fly a spacecraft around the moon until 2023. Maezawa announced Tuesday that he is inviting eight members of the public to join his DearMoon mission, which will be a six-day trip to the moon and back.

NASA rover Perseverance lands on Mars

NASA rover Perseverance lands on Mars

[This livestream has ended. A replay is available above]

TO UPDATE: NASA successful landed his Perseverance rover on the surface of Mars. Read more about it here.

NASA is hours away from its most ambitious Mars mission to date. The US space agency will attempt to land the Perseverance rover after a journey of more than six months on the red planet.

Perseverance was built by NASA’s Jet Propulsion Laboratory in California and is the fifth and most technologically advanced rover the agency plans to deploy on the surface of Mars for nearly two years. The rover and its spaceship are equipped with two dozen cameras to capture its expedition. The robot is full of scientific instruments to measure the geology of the planet – and hopefully collect samples that NASA hopes to return to Earth one day.

“Mars stimulates our imaginations and has been part of our dreams for many decades. The persistence balances the long history of systematic science-driven exploration of Mars,” said Dr. Thomas Zurbuchen, Deputy Administrator of NASA’s Directorate for Scientific Missions, in a briefing before landing.

The rover is scheduled to touch the surface at around 3:55 p.m. ET.

Since launching on a United Launch Alliance Atlas V rocket on July 30, Perseverance has traveled 293 million miles to reach Mars. The rover is about the size of a small car, weighs about a ton in total, and is 10 feet long by 9 feet wide by seven feet tall. It has a robotic arm that is about 7 feet long, the end of which has a robotic hand that has a camera, chemical analyzer, and rock drill.

“We want to land on Mars … and with the cameras turned on so that the whole world is inspired by us,” said Zurbuchen.

The landing will include what NASA engineers call the “Seven Minutes of Terror”. This is the time it takes to enter the Martian atmosphere and descend to the surface. It is known as such because it takes 11 minutes for communication to occur from the rover back to Earth. This means that the spacecraft and the rover have to land autonomously for the time delay.

Erisa Stilley, co-head of entry, descent and landing systems at NASA’s JPL, explained how the landing process is carefully coordinated after the rover has come through the atmosphere.

“Once the persistence on the parachute drops, we can now let go of the heat shield that protected us on entering and for the first time. [autonomously] Turn on the radar and look at the ground, “Stilley said in a pre-landing briefing.

Perseverance then uses a map on board and searches an area of ​​property worth about 120 soccer fields on the surface to find the safest place to land.

“That happens in the 2.4 seconds it takes endurance to send commands to separate from the rear hull and free fall,” said Stilley.

“When we have this knowledge and we are done with our free fall, we will fire the missiles,” added Stilley. “We’re going from 170 mph to about two at this point [miles per hour] while we slow down and prepare for the ‘sky crane’ maneuver. “

Persistence will take photos in entry time, which Stilley said NASA is hoping to “produce some images we’ve never seen before”.

The rover wants to land in the Jezero crater, a 45 km wide basin in the northern hemisphere of Mars. It’s a place NASA believes a body of water the size of Lake Tahoe was flowing. NASA’s science team is hoping that the ancient river delta may have received organic molecules and other potential signs of microbial life that Perseverance will attempt to detect with its instruments.

NASA invested around $ 2.4 billion to build and launch the Perseverance mission. Another 300 million US dollars are to land and operate the rover on the surface of Mars.
