Insights

Released in 1980 and now retired, Mobile Lab (6901) draws continued collector interest for its classic Space printed elements and red-and-white astronaut figures, and scarce sealed examples support steady post-retirement demand while vintage-market volatility and limited remake risk temper expectations.

Set Facts

It includes a small laboratory on six wheels and a red and white classic spaceman minifigures.
This set was the second largest Space set released in 1980, even though it only contained 135 pieces.

“6901 is celebrating its 40th birthday this year and I think it holds up well in terms of build experience. There's nothing tricky here, but it is an enjoyable build. If we were in 1980, I could definitely recommend the 6901 for the RRP, but at today's market prices (if you... More can find one), not so much.”

Full review at brickset.com

“Elevated vehicle with opening side doors, radar, articulated arm that could hold either a sensor array or a shovel with two astronauts and a pair of accessories. There’s nothing inside the vehicle (other than a steering wheel) to make it a lab. It can’t fit both the second... More astronaut and the sensor array at the same time. It looks a bit ridiculous with those 12 tiny wheels.”
