Salon has an article on Ingenuity.
In 1903, Orville and Wilbur Wright flew a plane for 12 seconds, 120 feet in the air, on what is now known as the first powered-controlled flight on Earth. Now, 118 years later, the first powered-controlled attempt at a flight on another planet is about to take place.
According to NASA, Ingenuity — the four-pound rotorcraft attached to Perseverance — is on its way to its "airfield" on Mars.
The space agency announced that its target for its first takeoff attempt will happen no earlier than April 8, 2021.
Ingenuity was designed as an experiment to see if it is possible to fly on Mars as we do here on Earth. And the process leading up to the takeoff is a very meticulous one. Consider how long it took humans to stick a powered-controlled flight on Earth; given Mars' thin atmosphere and a twenty-minute delay in communication, it is arguably more challenging on Mars.
"As with everything with the helicopter, this type of deployment has never been done before," Farah Alibay, Mars helicopter integration lead for the Perseverance rover, said in a press statement. "Once we start the deployment there is no turning back."
Every move for the next couple of weeks could make or break Ingenuity's success — starting with precisely positioning the rotorcraft in the middle of its 33-by-33-foot square airfield, which is actually a flat field on the Martian surface with no obstructions. From there, the entire deployment process from Perseverance will take about six Martian days, which are called sols. (The Martian sol is thirty-nine minutes longer than an Earth day.)
Good luck, little chopper!

They're not that severe. It's just mass.
In other words, NASA gets an adequate budget, it's just flushed on bad efforts as Socrastotle noted.

Mass costs money to deliver and they have payload limits to consider. SLS block 1 is expected to put 57k pounds into lunar orbit for 'only' $2 billion, and they hope to be able to launch once per year once they get production issues sorted out. That is over $35k per pound and only covers launch costs. Payload to Mars should be even less for the same money, and that one launch per year also covers lunar missions and other deep space operations. At that cadence and with a Mars launch window every 18 months then we can expect at most one Mars launch every three years. There are reasons that NASA is talking about going to Mars in the 2030's at the soonest. Frankly the 2040's is probably overly optimistic.
For comparison: Assuming worst case pricing of $100 million per launch and limited to a single tower, for the same price as one SLS launch SpaceX should be able to launch 10 Starships, and 1 Starship tanker ten times, sending 1500 tonnes, or 3.3 million pounds, to Mars each 18 month window. That is the difference that flushing your money has on how much mass you can send.

And IMHO SpaceX could do that with a few year build up. No screwing around for another 30 years, start making it happen in say the 2024 launch window (there's a lot of build up that needs to be done to any serious Mars effort, including technology demonstrations).
