Saturday SpaceX launch weather forecast: More showers, thunderstorms likely at Cape Canaveral. “You see people going into that rocket, that is something special. Still, forecasters can look at the overall pattern to see if conditions present themselves for thunderstorm development. Doyle Rice. (CNN)Weather again threatens the launch window for a SpaceX rocket to carry NASA astronauts on the first crewed spaceflight to take off from US soil in nearly a decade. Delay probability of violating launch weather constraints: 40%, Primary concern(s): Anvil Cloud Rule, Thick Cloud Layer Rule. The main trigger for showers and storms over the weekend will be a cold front approaching Florida from the northwest. “All the teams are go,” said Kathy Lueders, NASA commercial crew program manager. A SpaceX rocket is scheduled to blast off Wednesday afternoon from Kennedy Space Center, but a line of storms is also expected to move through the area. The Countdown: What does geography say about political strategy? A prelaunch NASA technology show is scheduled for Sunday, June 23 at noon from Kennedy. ET, with a backup window of 3 p.m. Forecasters also have to monitor the winds. It isn't always easy to forecast precisely where one of these storms will pop up. However, the forecast for launch day was improving.

Meteorologists with the U.S. Air Force 45th Space Wing predict a 70% chance of favorable weather Monday, June 24, for launch of the Department of Defense Space Test Program-2 mission on a SpaceX Falcon Heavy rocket. Special Support . Forecast Details In 1987, the unmanned Atlas/Centaur-67 rocket was launched into rainy, overcast skies when lightning struck, sending it “tumbling out of control,” according to Reuters. NASA missions and other highlights on this mission include: For additional information about the NASA technologies aboard the launch, visit: www.nasa.gov/spacex, Your email address will not be published. If there is a sustained wind of 30 mph or more at 162 feet above the launch pad, the mission will be canceled.

The weather may not be … The SpaceX Falcon 9 rocket is planned to launch from Kennedy Space Center in Florida on Wednesday at 4:33 p.m. Falcon Heavy L-1 Weather Forecast: 70% Chance Favorable . As of Saturday morning, the 45th Weather Squadron of the U.S. Space Force was forecasting a 50% chance of weather being favorable at the launch … the 45th Space Wing Weather Squadron states. In its briefing posted Friday morning, the Weather Squadron made clear that its weather concerns for Saturday and Sunday are the same as those which foiled Wednesday’s launch attempt, namely the possible presence of showers and thunderstorms in the vicinity of the launch site, and tall cumulus clouds which can be a source of turbulence and lightning. The rocket launch will send astronauts Bob Behnken and Doug Hurley aboard SpaceX’s Crew Dragon spacecraft to the Space Station. The weekend launch could be aborted if any of a dozen weather rules are violated for various cloud, wind and precipitation scenarios. That front probably won’t clear the Space Coast until sometime Monday. "Weather is the one thing that we actually cannot control on our missions so unfortunately, it did cause us to scrub today," tweeted NASA. But this will be a major test for the Commercial Crew Program, through which the space agency is contracting with SpaceX and Boeing to resume crewed space flight from U.S. soil after years of hitching an expensive ride aboard Russian rockets. “It’s a lengthy process to get to the best result.”, Neither NASA nor SpaceX have specified how many abort sites must have acceptable weather for a launch to proceed. Lueders said the Falcon 9 static-fire test on May 22, part of standard pre-launch preparations for any Falcon 9 mission, went as planned, as did a “dry dress” rehearsal May 23 that served as a walk-through for Behnken and Hurley, who put on their pressure suits and boarded the spacecraft on the launch pad. Required fields are marked *. ET -- the first manned rocket launch from the US in nearly a decade. "Saturday and Sunday could turn out to have very similar weather as Wednesday did," CNN meteorologist Haley Brink said, referring to. For example, lightning in the area will cancel a flight, as will a cloud with a large enough electrical field to produce rocket-triggered lightning. NASA will stream the briefing live at https://www.nasa.gov/live. But the timing had to be just right for a proper rendezvous with the International Space Station. ET on Sunday.

Historic SpaceX launch postponed because of stormy weather Marcia Dunn, Associated Press 5/27/2020. Launch Forecast FAQ . Delayed from Oct. 20 due to poor weather forecast. They include wind sensors, lightning detection systems, a surface electric field system and radar. pic.twitter.com/4aIGKo39dZ. Launch weather officers must be "clear and convinced" that no NASA "criteria are violated in order to give the weather GO call for launch,". Safety officers were forced to divert and destroy the rocket so its debris would not land in civilian areas. “For me, this was a little bit of a turning point,” Koenigsmann said of observing that dress rehearsal.

Weather permitting, NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX's Crew Dragon spacecraft, lifting off on a Falcon 9 … This is a slight improvement over Wednesday’s forecast, which assigned a 60 percent chance of unfavorable weather. “We have a really complicated way of weighing different locations depending on how much risk they have in terms of an escape,” said Hans Koenigsmann, vice president of build and flight reliability of SpaceX. The 50% chance of a weather violation is about even with the weather forecast SpaceX and NASA were facing with the first launch attempt, and is a slightly better forecast … “We provide some guidance and some weather parameters to the SpaceX team, and they calculate the probability of all those abort points,” McAleenan said. “Certainly it’s been trending better over the last day or two for launch weather,” he said, concluding that the next forecast will project a 60% chance of acceptable weather.

Prelaunch Technology Show: Today, June 23 “[D]eep moisture will remain in place this weekend … with rain chances well above normal,” it wrote in its forecast discussion. "Either type of lightning could cause serious damage to the rocket and endanger public safety," the weather squadron states. “Although it seems a welcome drying trend over Florida will soon be upon us, it’s not clear if the timing will be soon enough for Sunday’s attempt,” the Weather Squadron wrote. Mike McAleenan, launch weather officer for the 45th Weather Squadron, said at the briefing that a “dynamic situation” had been unfolding over the last few days, including heavy rains at the Florida launch site the day of the review. During Wednesday’s scrubbed launch, three weather rules were violated, including the presence of natural lightning and an attached anvil, which is the top of a towering thunderstorm that can generate an electric field and trigger lightning when in contact with a rocket’s plume. Ocean conditions along the flight path, however, are not predicted to be out of the ordinary, with waves mostly in the range of three to six feet.
