Another SpaceIL's issue bites the dust
Dust is the number one enemy of every house on the planet. Not to mention those who suffer from allergies. On our planet, it's pretty simple: you just take a broom and a dustpan, and you're done. But for our engineers, the dust (aka "rock dust") on the surface of the moon is far from being a nuisance that can be solved with a damp cloth and a cleaning spray. There are several problems that dust might cause, which our Mission Analysis team is currently confronting:
First, the dust may cover the camera and cause blurring of images broadcast back to Earth while landing. Secondly, the dust may cause damage to the spacecraft, due to abrasion of its surface and various parts of the spacecraft. Likewise, the dust could sabotage the motion of the spacecraft's moving parts due to the penetration of dust particles different places. Penetration of dust particles may also damage the insulation and the ability evaporation of heat from the spacecraft. Dust may also create a 'vacuum' effect that will glue of the spacecraft's legs to the surface of the moon, or even stick to the solar panels and impair their effectiveness.
Today we are facing the consequences of all these expected problems and examine their impact on the spacecraft and mission. Among the ways being examined now include solutions such as removing the camera covers just after landing and only when it's time to document; using special material that repels and prevents adhesion of dust particles before the camera; using a kind of "shoes" on the ends of legs spacecraft and release when the spacecraft needs to "jump" after landing - to avoid vacuum; and even use gas spray, like the kind used for washing cars.
