"There is content filtering in the Market settings. If this some how got changed than the apps described wouldn't be allowed to be installed. All apps are rated according to a guide that Google has set up. Those ratings need to follow these guidelines:
Everyone
Applications in this category should not collect user’s location data or contain objectionable material. Applications should not share user content or include social features.
Low maturity
Applications in this category may include instances of mild cartoon or fantasy violence or other potentially offensive content. Applications may collect user location data for the purpose of providing location specific information or otherwise improving the user experience, but should not share the data with other users. Applications may include some social features but should not focus on allowing users to find and communicate with each other.
Medium maturity
Applications in this category may include sexual references; intense fantasy or realistic violence; profanity or crude humor; references to drug, alcohol and tobacco use; social features and simulated gambling. Applications may collect user location data for the purpose of sharing or publishing with the user’s consent.
High maturity
Applications in this category may focus on or include frequent instances of sexual and suggestive content; graphic violence; social features; simulated gambling; and strong alcohol, tobacco and drug references. Applications may collect user location data for the purpose of sharing or publishing with the user’s consent.
To change the content filtering in the Market open Market and tap: Menu>Settings>Allow apps rated, and select show all apps. This will allow all apps to be able to be installed from the Market.
I don't know if this is your problem for sure or not, but it really seems to fit what is happening. Hope this helps."
I did as he said and noted there is an additional category - Show all applications. Checked this and was able to download and install Google Earth (and Sky Map). They both work perfectly now.
