several other changes / code sanitization.

there can be a wind (horizontal force), not just gravity (vertical one).

When incomplete: -100 pts for every wreck (3 lives)

score counting: 500 points for safe landing + 10 pts for every unit of fuel saved - 1 pt for every second of mission duration (when mission has been completed).

while having: b) X-velocity < 4, c) Y-velocity < 6

safe landing requires: a) Touchdown on landing area (thick black line).

Look for 'groundline' in the code and notice that the canvas line command is incomplete.

some additional sanitization of the code.

added restart with space bar (more comfortable restart with left thumb, if.

added sprite for 'wreck' (not especially fancy, but looks out like debris,.

Such way we've got smooth movement of our 'lander' Movement, the second one exclusively as 'main game loop' (reading controls, HE The lander lands outside the canvas ( ZB It was because the moon dust is very soft, so the lander partially digged in itself while landing ). Now the game can started again with key n. I movedĪt the end of the code in the proc new. HE : With ZB's change the game cannot started again with key n. prevents event-looping after the game has been ended already

refreshtime set in global variable ::afterTime and default to 500.

grouped some initialisation inside a proc.Bugfix second line: set ::gravY 0 => set ::gravX 0.It's amazing how much more fun it is when you add left and right thrust! That's 22 (base, no comments, no blanks) to 35 lines of code (with X thrust)! Changes It can also be used to demonstrate simple physics (gravity/acceleration, velocity, and position). (Please comment in the history based on what type of changes added - 'added $feature', 'fixed bug', 'added comments') The code will be presented piecemeal, in the history. “We stand ready to help NASA moderate its technical risks and solve its budgetary constraints and put the Artemis Program back on a more competitive, credible, and sustainable path,” Bezos said.Nedbrek - This page will document the development of a simple game, similar to the old games 'Moon Lander' and 'Hey! Taxi!'. Not every lawmaker was happy about the inclusion of the extra funding, however: Senator Bernie Sanders called it a “Bezos bailout,” but was ultimately unsuccessful in getting the extra funding stripped from the bill. The Senate recently passed a bill that would, among other things, require NASA to select two companies for the HLS lander – and the extra funds to do so, SpaceNews reported. Blue Origin argued that the contract requirements did not give companies an ability to “meaningfully compete.” GAO must rule on the protest by August 4.īlue Origin and Dynetics are not the only entities to support two contract awards. The company, along with Dynetics, filed protests with the Government Accountability Office just one week after the award was announced. This is not the first time that Blue Origin has publicly questioned NASA’s decision to go with just one vendor. In a document obtained by The Washington Post explaining the rationale behind selecting a sole vendor for the HLS contract, NASA admits that it’s “current fiscal year budget did not support even a single award.” In response, SpaceX updated its payment schedule so it would fit “within NASA’s current budget.” That the agency has severe budgetary constraints is no secret: Congress approved just $850 million for the HLS program in fiscal year 2021, far short of the $3.4 billion NASA requested. Bezos is now offering to cut that price tag by $2 billion. That company, headed by Elon Musk, proposed a $2.89 billion plan for its lander – around half of Blue Origin’s $5.99 billion proposal. As TechCrunch’s Darrell Etherington notes, it’s not uncommon for NASA to select two vendors, as it did when it awarded both Boeing and SpaceX contracts under its Commercial Crew program.īut a year later, in a move that veered from historical practice, NASA announced it had selected just one company for the contract: SpaceX. NASA announced in April 2020 that Blue Origin, SpaceX and Dynetics were chosen for the initial phase of the contract, and it was thought that the competition would likely be whittled down to two final companies to build lunar landers.

The specific contract in question relates to developing a lunar lander for the Human Landing System program, which aims to return humans to the moon for the first time since the Apollo days. Jeff Bezos, the billionaire founder of Blue Origin, is offering to knock up to $2 billion off the cost of developing a lunar lander and to self-fund a pathfinder mission in exchange for a NASA contract.
