Name of a YA sci fi anthology?
I have been trying to locate an anthology of young-adult sci fi short stories that I read in primary school in the late '90s (I do not know when the book itself was published). I can only remember a few elements:
1. A story featuring an astronaut working on the Moon, who is caught in a blast and discovers a blinded and disoriented person who is recovering from it. He has a long chat with this person, who (unaware his savior is a human) openly states that he and his fellow aliens are planning an invasion of Earth.
2. A story involving a spacecraft getting caught in an event horizon. The story ends with people in another ship watching as the first ship undergoes spaghettification.
3. A story involving a group of commandos (the leader of which is distinct by wearing black, and his 2IC in brown), attacking some large ground craft (with tank-like tread) and eventually taking it over. 944
They then drive it to the enemy base pretending that the enemy side had won the engagement. One thing they did was lay out the bodies of dead commandos (along with fake-dead ones) on the front of the vehicle as they approached the base, to 'show the trophies' of the 'enemies' they'd killed, and once inside they leap up and begin attacking (a sort of Trojan Horse arrangement). The plan sort of works and a fierce fight breaks out; all the team are killed except their deputy leader; each of them (leader and 2IC) have a very powerful bomb (there are only two available), and the lone survivor uses his to detonate the base in a suicide run.
4. A story of two people who get on a spacecraft or rocket that sends them to a planet filled with nature with no other humanoids. For some reason, water causes their tunics and other clothes to melt away. Their craft cannot be used anymore so they are stranded on this planet. It is then revealed that they are <PERSON> and <PERSON>.
The cover art of the one I was reading featured a large greyish land vehicle like the one described in 3. I remember there also being a lot of yellow used on the cover. 322
