Astronauts arrive for NASA's 1st home launch in decade – CTV News

Published

CAPE CANAVERAL, FLA. —
The two astronauts who will end a nine-year launch drought for NASA arrived at Kennedy Space Center on Wednesday, exactly one week before their historic SpaceX flight.

It will be the first time a private company, rather than a national government, sends astronauts into orbit.

NASA test pilots Doug Hurley and Bob Behnken flew to Florida from their home base in Houston aboard one of the space agency’s jets.

“It’s an incredible time for NASA and the space program, once again launching U.S. crews from Florida and hopefully in just a week from about right now,” Hurley told reporters minutes after arriving.

Hurley was one of the four astronauts who arrived at Kennedy on July 4, 2011, for the final space shuttle flight, “so it’s incredibly humbling to be here to start out the next launch from the United States.”

“We feel it as an opportunity but also a responsibility for the American people, for the SpaceX team, for all of NASA,” Behnken added.

The two are scheduled to blast off next Wednesday afternoon atop a SpaceX Falcon 9 rocket, bound for the International Space Station. They’ll soar from the same pad where Atlantis closed out the shuttle program in 2011, the last home launch for NASA astronauts.

Since then, the only way to the space station for astronauts has been on Russian rockets launched from Kazakhstan.

Hurley and Behnken still don’t know how long they’ll spend at the space station: anywhere between one and four months. Only one American is up there right now — astronaut Chris Cassidy — and could use a hand. Hurley said he got an email from Cassidy on Tuesday night in which he wrote that “he’s looking forward to seeing our ugly mugs on board.”

Greeting the astronauts at Kennedy’s former shuttle landing strip were the centre’s director, former shuttle commander Robert Cabana, and NASA Administrator Jim Bridenstine.

“You really are a bright light for all of America right now,” Bridenstine told them.

The welcoming committee was reduced drastically in size because of the coronavirus pandemic. There were no handshakes for the astronauts, who did not wear masks but kept their distance at separate microphones. Cabana and Bridenstine wore masks except while addressing the crowd; so did the approximately 20 journalists standing more than 20 feet (6 metres) away.

During these tough times, Bridenstine said, “this is a moment when we can all look and be inspired as to what the future holds.”

NASA’s commercial crew program has been years in the making. Boeing, the competing company, isn’t expected to launch its first astronauts until next year.

As the trailblazers, Hurley and Behnken are establishing new prelaunch traditions. They shared two at Bridenstine’s request Wednesday.

Hurley, a former Marine and fighter pilot, followed military tradition and put a mission sticker on the SpaceX flight simulator in Houston on Tuesday, after completing training. Behnken, an Air Force colonel, followed Russian custom and planted a tree. He had help back home from his wife, who’s also an astronaut, and their 6-year-old son.

“My son will always have that lemon tree that he was a part of planting,” Behnken said. “Hopefully, it makes it through Houston’s hot summer this year and becomes a tradition for some other folks as well.”

SpaceX’s historic NASA astronaut launch debut on track for second attempt – Teslarati

Published

on



Rather than making history on May 27th, SpaceX’s highest-profile launch ever – Crew Dragon’s NASA astronaut launch debut – was scrubbed just minutes before liftoff by stormy Florida weather. Unfortunately, conditions appear to be even less favorable on Saturday and Sunday backup windows.

Weather trended well, until it didn’t

The day began with launch fans growing increasingly concerned about a system of low-pressure off of Florida’s northeast coast that strengthened into tropical storm Bertha – the second named storm before the official start of the Atlantic basin hurricane season on June 1st. As the day progressed, Bertha became less of a worry for SpaceX recovery and emergency abort drop zones as it moved further north up the coast eventually making landfall in South Carolina. Then the thunderstorms began firing up.

Going into launch day launch weather officer, Mike McAleenan of the U.S. Space Force’s 45th Weather Squadron predicted a 60% chance of favorable launch weather conditions. That decreased slightly to 50% during the morning’s launch weather briefing. The 50/50 shot of Florida weather cooperating to get the launch off during the one-second long launch window opportunity remained the main concern for the rest of the day.

During the final thirty minutes of the countdown, many of the weather constraints that were holding up a green-light for launch from cleared up, but one last weather rule remained no-go. McAleenan stated over the internal weather communication loop during NASA’s live broadcast that if the launch window could’ve extended another 10 minutes, the weather would probably cooperate. This wasn’t the case, though. The launch attempt was ultimately aborted just 14 minutes shy of liftoff due to the “field mill” rule not clearing in time. The lightning field mill rule refers to a sophisticated electrical field system that spans the entire area of Kennedy Space Center and the surrounding area of Cape Canaveral responsible for continuously detecting the electrical charge of the atmosphere.

Protecting rockets from producing lightning

Rockets are not permitted to launch through an electrically charged atmosphere because of the possibility of what is called “triggered” lightning – lightning that is actually produced by a rocket bursting through an electrically charged atmosphere. Sending a rocket through an already unstable atmosphere can cause a disturbance, a lightning bolt, to be triggered. This phenomenon has the capability of being potentially dangerous for the rocket and, more importantly in this case, the occupants on board.

Demo-2, Round 2

Following a scrubbed first attempt, the 45th Weather Squadron released the L-3 (3 days until launch) forecast for the second attempt to send NASA astronauts Doug Hurley and Bob Behnken to the International Space Station. The prediction looked much like the one going into Wednesday’s attempt. On Thursday morning, May 28th, a new L-2 (2 days until launch) forecast was released showing very little change from the evening before.

SpaceX’s next attempt at a Demo-2 launch will occur on Saturday, May 30th, at 3:22:41pm EDT with another backup attempt scheduled for Sunday, May 31st at 3:00:07pm EDT. The outlook for the weather, however, looks much the same as it did for Wednesday. The 45th Weather Squadron is currently predicting only a 40% chance of favorable launching conditions on both days, and that’s just for the weather directly over LC-39A at the time of launch.

A L-3 weather forcast provided by the U.S. Space Force’s 45th Weather Squadron outlines a 40% chance of acceptable weather conditions at time of launch for SpaceX’s back-up attempt to lauch the first ever crewed mission, Demo-2, on Saturday, May 30th. (Credt: U.S. Space Force – 45th Weather Squadron)

The 45th Weather Squadron does not predict other conditions that can determine a scrub of launch including upper-level atmospheric winds capable of completely sheering apart a rocket at altitude, or weather conditions for booster recovery and the recovery zones needed to rescue the Dragon capsule in the event of an emergency abort scenario. SpaceX has its own team of professionals that work in tandem with the 45th Weather Squadron to monitor the conditions of the recovery and abort zones. SpaceX takes things into consideration like wave height and patterns to determine whether or not conditions are appropriate enough for crews to perform any and all recovery operations that may be needed.

For Saturday’s attempt, the SpaceX Demo-2 will once again face the challenges of precipitation and dangerous lightning producing anvil and cumulus clouds. Expect launch day to look much like it did during the first attempt on Wednesday. SpaceX will need to thread one seriously precise needle to pull off the most historic rocket launch in company history.

Tesla's Musk earns $770M in stock options, company confirms – OttawaMatters.com

Published

on


DETROIT — Tesla confirmed Thursday that CEO Elon Musk will get the first tranche worth nearly $770 million of a stock-based compensation package triggered by the company meeting several financial metrics.

The electric car and solar panel maker’s board certified that Musk earned the big payout, according to a filing with the U.S. Securities and Exchange Commission. The filing says Musk can buy 1.69 million shares of Tesla stock for $350.02 each, but it wasn’t clear whether he had exercised the stock options. His payout is based on the difference between the option price and Thursday’s closing share price of $805.81.

Musk earned the options as part of an audacious compensation package approved by the board in 2018.

According to the filing, the board certified that Tesla had reached the milestones by hitting $20 billion in total revenue for four previous quarters and a total market value of $100 billion. The company also reached $1.5 billion in adjusted pretax earnings, but that must still be certified by the board, the filing said.

Musk has to hold the stock for a minimum of five years, under the terms of the compensation package.

Musk can afford to wait before cashing in on his latest windfall, given his wealth is estimated at $39 billion by Forbes magazine.

All told, the incentives approved by Tesla’s board in 2018 consist of 20.3 million stock options that will be doled out in 12 different bundles if the company is able to reach progressively more difficult financial goals. It’s one of the biggest corporate pay packages in U.S. history.

In order for Musk to receive all 20.3 million stock options, Tesla will have to generate adjusted annual earnings of $14 billion on annual revenue of $175 billion coupled with a market value of $650 billion. In the past four quarters, Tesla, which is based in Palo Alto, California, has reported adjusted earnings totalling $3.6 billion on revenue totalling $26 billion.
